The pharmaceutical-grade Cephalexin ensures targeted action against harmful bacteria, promoting faster recovery and minimizing harm to beneficial aquatic life.
Can Fish Flex Cephalexin treat internal infections in fish?
Yes, Fish Flex Cephalexin is effective against many internal infections caused by harmful bacteria. It can be administered via food to target internal issues like ulcers and systemic infections. Always consult a veterinarian for proper diagnosis and dosage.
How does Fish Flex Cephalexin compare to other fish antibiotics?

Regular price $18.95 Save $-18.95Fish Cephalexin Capsules - Fish & Bird Antibacterial Treatment 250 mg / 500 mg
Fish Flex (Fix Flex) is an antibacterial treatment in capsule form for ornamental aquarium fish and non-food pet birds.
Made by Aqua Soma Labs, it supplies cephalexin in 250 mg and 500 mg capsule strengths and is available in bottles containing 30 or 100 capsules with clearly printed expiration dates.
Often called Fish Flex, Fin Flex, or simply fishflex in the aquarium community, this product is an online alternative to discontinued Thomas Labs Fish Flex, Fish Flex Forte, Fish Aid Cephalexin, Aqua Ceph 500 mg, Aqua Flex, and FISHBIOTIC Cephalexin products.
Aquarium keepers may also search for it as fish cephalexin, fish cephalexin 500 mg, or cephalexin for fish.
It is used to help manage common bacterial concerns such as fin and tail rot, skin ulcers, infected wounds and lesions, red patches, pop-eye, and dropsy or pinecone disease in freshwater and saltwater aquariums.
Under veterinary guidance, bird keepers may also use cephalexin as part of a treatment plan for bumblefoot, skin infections, or joint infections in pigeons and other non-food pet birds.
The capsules can be opened so the powder disperses quickly through aquarium water in a separate hospital or quarantine tank.
The availability of two strengths and two bottle sizes gives aquarium and bird keepers flexible options, whether maintaining one hospital tank, several community aquariums, or a veterinarian-directed aviary treatment plan.
Consider treatment when early signs of bacterial stress appear, including ragged fins, red or pale fin edges, open sores, localized swelling, cloudy body patches, pop-eye, or persistent appetite loss.
Fish-Specific Symptoms
- Fin and tail rot with frayed or ragged fins
- Skin ulcers, open sores, and infected wounds
- Red or cloudy patches on the body
- Pop-eye or exophthalmia

Addressing possible bacterial problems early, together with suitable water quality, good housing, reduced stress, and advice from an aquatic or avian professional, helps maintain a stable aquarium or aviary.

Fish Flex vs Fix Flex: What Changed?
If you previously purchased Thomas Labs Fish Flex, Fish Flex Forte, Aqua Ceph, Aqua Flex, or FISHBIOTIC Cephalexin, here is what has changed and what remains the same.
Same Cephalexin
Fix Flex contains cephalexin in the same familiar 250 mg and 500 mg capsule strengths associated with older Fish Flex and Aqua Ceph products.
New Manufacturer
Fix Flex is made in the United States by Aqua Soma Labs, replacing the discontinued Thomas Labs line.
Same Capsule Form
The capsules can be opened so the powder can be mixed into aquarium water or administered to birds exactly as directed by an avian veterinarian.
Two Strengths and Two Bottle Sizes
Choose 250 mg or 500 mg capsules in 30-count or 100-count bottles according to the aquarium volume and treatment plan.
Benefits of Fix Flex for Fish & Birds
Bacterial Support for Fish and Birds
Fix Flex provides cephalexin for ornamental aquarium fish and non-food pet birds and may help manage fin and tail rot, skin ulcers, infected wounds, red patches, and other bacterial concerns when used as directed.
Made in the United States
Fix Flex is manufactured in the United States by Aqua Soma Labs, with clear strength labeling and expiration information on each bottle.
Two Strengths to Match Your Tank
Choose 250 mg capsules for smaller treatment systems or 500 mg capsules for larger water volumes while following the product label.
Consistent Capsules
Each capsule provides a consistent amount of cephalexin, making aquarium-volume calculations easier across quarantine tanks and larger treatment systems.
Easy to Prepare
Capsules can be opened and the powder mixed with aquarium water, helping distribute the treatment evenly while limiting unnecessary handling of stressed fish.
Freshwater, Saltwater & Aviary Setups
Fix Flex may be used in properly prepared freshwater or marine hospital tanks and in veterinarian-directed treatment plans for pigeons and other ornamental birds.
Good for Hospital Tanks and Quarantine
A separate treatment system protects the main aquarium's biological filtration and reduces unnecessary exposure of healthy tank mates and sensitive invertebrates.
Usage Guidelines & Instructions
Set Up a Separate Treatment Area
Move affected fish to a dedicated hospital or quarantine tank before treatment.
Where practical, birds receiving veterinarian-directed treatment should be separated into an appropriate treatment enclosure.
Separation helps protect healthy animals and allows more accurate treatment and observation.
Choose the Right Strength
Fix Flex is available in 250 mg and 500 mg capsule strengths.
Select the strength that matches the treatment-tank water volume or the instructions provided by a qualified professional.
Do not increase the amount, shorten the interval, or extend treatment beyond the label directions.
Directions for Fish Aquariums
Add one dissolved 250 mg dose per 10 gallons or approximately 38 litres of treatment water.
Open the capsule, stir the powder into a clean cup of aquarium water, and distribute the prepared solution evenly throughout the hospital tank.
Repeat every 24 hours for 5 to 10 days, performing a partial water change between treatments.
Discontinue treatment and consult an aquatic veterinarian if no improvement is seen within five days.
Use in Pet Birds Under Veterinary Guidance
Only administer cephalexin to pigeons and other non-food pet birds under the direction of an avian veterinarian.
The veterinarian should determine the correct amount according to the bird's species, weight, condition, frequency, and treatment duration.
Capsule contents may be mixed with soft food or drinking water only as specifically instructed.
Maintain Water Quality & Complete Treatment
Perform partial water changes when needed between treatments to keep ammonia and nitrite low.
Maintain stable temperature and strong aeration throughout the treatment period.
Complete the full label-directed treatment unless a veterinarian advises otherwise.
Seek professional guidance if symptoms become worse or fail to improve.
Fix Flex Amounts by Aquarium Size
| Tank volume | Cephalexin per use | 250 mg capsules | 500 mg capsules |
|---|---|---|---|
| 10 gallons (38 L) | 250 mg | 1 capsule | Use the 250 mg strength |
| 20 gallons (76 L) | 500 mg | 2 capsules | 1 capsule |
| 30 gallons (114 L) | 750 mg | 3 capsules | 1 capsule plus one 250 mg capsule |
| 40 gallons (151 L) | 1,000 mg | 4 capsules | 2 capsules |
| 55 gallons (208 L) | Approximately 1,375 mg | 5 to 6 capsules | Approximately 3 capsules |
What to Expect During Treatment
Days 1 to 2
Fish may hide, eat less, or produce slightly cloudy treatment water. Maintain strong aeration and continue monitoring water quality.
Days 3 to 5
Look for sores and red patches that stop spreading, returning appetite, improved activity, and steadier breathing.
Days 5 to 10
Complete the recommended treatment even when improvement appears. After treatment, perform a partial water change and restore activated carbon.
What You Need for Treatment
Prepare the following supplies before the first treatment:
- A separate hospital or quarantine tank
- A suitable aquarium heater
- An air stone or established sponge filter
- An ammonia and nitrite test kit
- A suitable water conditioner or dechlorinator
- A small net for gentle fish transfer
- A clean cup for mixing each treatment
Pro Tip: Quarantine affected fish and birds away from healthy companions whenever practical. A dedicated treatment setup with stable temperature, strong aeration, and no substrate makes observation and water changes easier.
How Fix Flex Works
Fix Flex supplies cephalexin as the active ingredient at a strength of 250 mg or 500 mg per capsule.
Cephalexin works against a range of susceptible Gram-positive bacteria and some Gram-negative species that may affect the skin, fins, wounds, and soft tissues of ornamental fish and non-food pet birds.
In practical terms, it helps slow or stop the growth of susceptible bacteria so the animal has a better opportunity to recover when the underlying condition is bacterial.
Each hard capsule contains cephalexin powder together with standard inactive ingredients that support capsule stability and help the contents disperse when mixed into aquarium water.
Administration to birds should follow the exact method and amount provided by an avian veterinarian.
Safety and Tank Notes
When used as directed, Fix Flex generally causes no problems in ornamental aquarium fish and non-food pet birds.
Incorrect amounts, unnecessarily prolonged use, or repeated antibacterial treatment may increase the risk of unwanted reactions and bacterial resistance.
Fish
Cephalexin treatment may cause temporary hiding, mild treatment-water cloudiness, reduced activity, or appetite loss.
If severe distress appears, including rapid gill movement, surface gasping, loss of balance, or remaining on the bottom, stop treatment, improve aeration, perform an appropriate water change, and seek aquatic veterinary advice.
Birds
Possible reactions may include reduced appetite, loose or changed droppings, and lethargy, particularly when the amount is too high or the bird is sensitive.
If a bird becomes fluffed up, inactive, has difficulty breathing, or stops eating, discontinue treatment and contact an avian veterinarian.
Invertebrates
Do not use Fix Flex in display aquariums containing shrimp, snails, corals, or other sensitive invertebrates whenever a separate hospital tank is available.
Strong antibacterial treatment may harm sensitive species or disrupt the aquarium ecosystem.
Safe Use in Your System
Remove activated carbon and switch off UV sterilization during treatment.
Monitor ammonia, nitrite, temperature, and oxygen levels closely.
Do not combine Fix Flex with other treatments unless specifically advised by a qualified veterinarian.
Important Safety Warning
Fix Flex is intended for ornamental aquarium fish and non-food pet birds only. It is not intended for animals raised for food.
Store the capsules in their original container in a cool, dry location protected from direct sunlight, excessive heat, and moisture.
Keep the container tightly closed and out of reach of children and animals.
Always follow the current product-label directions.

Fish Fluconazole 100mg (Fish Flucon) | Fish Antifungal
Regular price $51.99 Save $-51.99Fish Fluconazole 100mg (Fish Flucon) | Fish Antifungal
Fish Flucon (Fix Flucon) is a fluconazole-based antifungal treatment formulated for ornamental aquarium fish.
Each tablet contains 100 mg of fluconazole and is designed to dissolve in treatment water for aquarium fish showing signs consistent with a susceptible fungal problem.
Fix Flucon is commonly considered for topical fungal growths visible on the skin, fins, mouth area, or damaged tissue, as well as certain systemic fungal concerns affecting ornamental fish.
Aquarium keepers may recognize this type of product under older names such as Fish Flucon, Fish Fluconazole, Aqua Flucon, or aquarium fluconazole.
Fix Flucon is the current Aqua Soma Labs version supplied in a clearly labeled 100 mg tablet strength.
Fluconazole is an antifungal ingredient rather than an antibacterial. It is intended for susceptible fungal organisms and should not be expected to treat ordinary bacterial fin rot, columnaris, parasites, viral disease, or poor-water-quality problems.
Fungal growth often appears after an injury, stress event, poor water conditions, or another disease has damaged the fish's protective skin and slime coat.
Correcting water quality, reducing stress, maintaining suitable temperature, and identifying the underlying cause remain essential parts of treatment.
Begin by moving the affected fish to a separate hospital or quarantine tank whenever possible.
Visible External Signs
- White or gray cotton-like growth on the skin
- Fuzzy growth around damaged fins or wounds
- Fungal growth on an injured mouth area
- Pale or discolored patches that appear raised or wool-like
- Fungal growth around an ulcer or damaged scale
- Fin deterioration accompanied by visible fuzzy material
- Egg fungus in a separate breeding or treatment setup
Possible Systemic or Advanced Signs
- Persistent loss of appetite
- Progressive weight loss
- Reduced activity or unusual hiding
- Loss of normal coloration
- Abnormal or circular swimming
- Bulging eyes associated with a wider health problem
- Recurring lesions that do not improve after water correction
Use Fix Flucon alongside stable water conditions, strong aeration, suitable nutrition, and careful daily observation.
When the cause is uncertain, or the fish is deteriorating rapidly, consult an aquatic veterinarian or experienced fish-health professional.
Order online: In-stock orders ship from our United States warehouse according to the current store processing and shipping schedule.
Fish Flucon vs Fix Flucon: What Changed?
Aquarium keepers who previously purchased Fish Flucon, Fish Fluconazole, or similar aquarium fluconazole products can use the comparison below to understand the current Fix Flucon presentation.
Fluconazole 100 mg
Each Fix Flucon tablet provides 100 mg of fluconazole for aquarium antifungal use.
Aqua Soma Labs Fix Line
Fix Flucon is supplied under the Aqua Soma Labs Fix product line with updated branding and packaging.
Dissolvable Treatment Form
The tablet can be pre-dissolved in aquarium water before being distributed throughout a hospital tank.
10-Count Supply
The compact bottle is suited to a dedicated hospital tank, smaller aquarium setup, or short label-directed treatment plan.
Benefits of Fix Flucon for Aquarium Fish
Targeted Antifungal Ingredient
Fluconazole is formulated to target susceptible fungal organisms rather than bacteria, viruses, or parasites.
External and Systemic Fungal Support
Fix Flucon may be considered for visible fungal growth and certain deeper fungal concerns when the suspected organism is sensitive to fluconazole.
Consistent 100 mg Tablets
Each tablet supplies a fixed 100 mg amount, helping aquarium keepers calculate treatment according to the actual hospital-tank water volume.
Easy to Pre-Dissolve
Tablets can be mixed in a clean cup of aquarium water before being added evenly throughout the treatment system.
Useful for Hospital Tanks
A separate treatment tank allows closer observation while protecting healthy fish, sensitive invertebrates, and the display aquarium.
Freshwater and Marine Treatment Setups
Fix Flucon may be used in an appropriately prepared freshwater or saltwater hospital tank when consistent with the current label.
Clear Antifungal Purpose
The product provides an antifungal option for situations where visible growth or other signs suggest fungus rather than a bacterial or parasitic condition.
Usage Guidelines & Instructions
Quick Usage Summary
Pre-dissolve one 100 mg tablet for every 5 gallons or approximately 19 litres of treatment water.
Administer once every 24 hours for five consecutive days according to the current product directions.
Discontinue treatment and reassess the diagnosis if no improvement is noted after five days.
Confirm That the Problem Appears Fungal
Look for raised white, gray, or cotton-like growth attached to damaged skin, fins, wounds, or eggs.
Do not assume every white patch is fungus. Columnaris, excess mucus, parasites, and damaged tissue can appear similar.
Prepare a Separate Treatment Tank
Move affected fish to a hospital or quarantine tank whenever possible.
Maintain stable temperature, strong aeration, and suitable filtration without activated carbon.
Switch off ultraviolet sterilization during treatment unless the current product label directs otherwise.
Measure the Actual Water Volume
Calculate the amount of water actually being treated rather than relying only on the aquarium's advertised capacity.
Substrate, rocks, decorations, equipment, and the fill level reduce the real water volume.
Pre-Dissolve the Tablet
Place the required tablet amount in a clean cup containing aquarium water.
Mix thoroughly, then distribute the prepared solution evenly throughout the treatment tank.
Administer Once Every 24 Hours
Use one 100 mg tablet for every 5 gallons or approximately 19 litres of actual treatment water.
Repeat once daily according to the current label directions.
Continue for Five Consecutive Days
Continue treatment for five consecutive days while checking the fungal growth, appetite, activity, breathing, and water parameters.
Do not extend treatment beyond the current label directions without aquatic veterinary guidance.
Stop if There Is No Improvement
Discontinue use if no improvement is noted after five days.
Reassess the diagnosis because the condition may be bacterial, parasitic, viral, environmental, or resistant to the selected treatment.
Fix Flucon Amounts by Aquarium Size
| Tank volume | Fluconazole per use | 100 mg tablets |
|---|---|---|
| 5 gallons (19 L) | 100 mg | 1 tablet |
| 10 gallons (38 L) | 200 mg | 2 tablets |
| 20 gallons (76 L) | 400 mg | 4 tablets |
| 30 gallons (114 L) | 600 mg | 6 tablets |
| 40 gallons (151 L) | 800 mg | 8 tablets |
What to Expect During Treatment
Days 1 to 2
The visible growth may remain present while treatment begins. Fish may hide or eat less because of the illness or transfer to a hospital tank.
Days 3 to 4
Look for growth that stops spreading, appears reduced, or begins separating from damaged tissue. Appetite and activity may gradually improve.
Day 5
Complete the label-directed course and reassess. Stop treatment and seek professional guidance if there is no improvement or the fish become worse.
What You Need for Treatment
- A separate hospital or quarantine tank
- A suitable aquarium heater
- An air stone or established sponge filter
- An ammonia and nitrite test kit
- A suitable water conditioner or dechlorinator
- A small net for gentle fish transfer
- A clean cup for pre-dissolving the tablets
- Activated carbon for use after treatment, when appropriate
Pro Tip: Correct the underlying cause while treating the fungus. Check for sharp decorations, fighting, parasites, poor water quality, temperature stress, and injuries that may have damaged the fish's protective skin.
How Fix Flucon Works
Each Fix Flucon tablet contains 100 mg of fluconazole, a triazole antifungal ingredient.
Fluconazole interferes with the production of important sterol components used by susceptible fungal cell membranes.
Disrupting this process can limit fungal growth and give affected tissue an opportunity to recover when the organism is susceptible and the aquarium environment is stable.
Fix Flucon is intended for fungal concerns. It does not replace antibacterial treatments for bacterial infections and does not target parasites or viruses.
Treatment success depends on correct identification of the problem, appropriate water conditions, the health of the fish, and whether the organism is sensitive to fluconazole.
Standard inactive tablet ingredients help maintain tablet stability and allow the product to disperse after it is pre-dissolved in aquarium water.
Safety and Tank Notes
Use Fix Flucon only according to the current product label and monitor fish and water quality closely during treatment.
Incorrect amounts, prolonged treatment, unnecessary repeat courses, or combining products may increase stress and make it harder to identify the original cause.
Possible Fish Reactions
Sick fish may temporarily hide, eat less, or appear lethargic during treatment.
These signs may result from the underlying illness, transfer stress, water-quality changes, or treatment sensitivity.
Stop Treatment If
Stop treatment if fish develop severe weakness, rapid gill movement, surface gasping, loss of balance, rolling, or a rapid decline.
Increase aeration, perform an appropriate partial water change, and seek aquatic veterinary guidance.
Water Quality
Test ammonia and nitrite regularly and maintain stable temperature and oxygen levels.
Poor water quality can worsen fungal growth and prevent damaged tissue from recovering.
Filtration During Treatment
Remove activated carbon and other chemical filtration media during treatment because they may reduce the amount of product available in the water.
Switch off UV sterilization unless the current label directs otherwise.
Invertebrates and Reef Systems
Treat affected fish in a separate hospital tank rather than exposing shrimp, snails, corals, and other sensitive invertebrates.
Sensitivity may vary between species and aquarium systems.
Do Not Mix Treatments
Do not combine Fix Flucon with antibacterial, antiparasitic, or other antifungal treatments unless the product labels permit it or a qualified professional recommends the combination.
Important Warnings & Precautions
Aquarium use only: Fix Flucon is intended for ornamental aquarium fish.
Not for human use: Do not ingest the tablets or use them for human treatment.
Not for food fish: Do not use on fish or other animals intended for human consumption.
Storage: Keep the bottle tightly closed in a cool, dry location protected from direct sunlight, excessive heat, and moisture.

Fish Mox (Fix Mox) is a fish amoxicillin treatment in 250 mg and 500 mg capsules for ornamental aquarium fish and non-food pet birds.
In freshwater and saltwater tanks it is used for common bacterial problems including dropsy or body swelling, fin and tail rot, columnaris, hemorrhagic septicemia, red streaks, gill disease, swim bladder infections, abscesses, and skin ulcers.
With an avian veterinarian's guidance, the same capsules can be part of an amoxicillin plan for problems such as crop infections and salmonella or paratyphoid in pigeons and other pet birds.
Fix Mox gives you a 250 mg or 500 mg strength, so you can match it to the job: a small hospital tank, a larger community aquarium, or, with veterinary input, a loft or aviary.
It is the current replacement for the discontinued Thomas Labs Fish Mox, also known as fishmox. The 250 mg option stands in for the original strength, and the 500 mg option covers what aquarists knew as Fish Mox Forte and Aqua Mox.
Stock ships from our United States warehouse with fresh expiration dates and clearly printed strengths.
Start treatment early, at the first signs of bacterial stress. Those signs differ between fish and birds, so use the lists below to know what to watch for.
Fish-Specific Symptoms
- Fin and tail rot, including frayed or rotting fins
- Dropsy or body swelling
- Pop-eye or bulging eyes
- Red streaks or open sores on the body
- Skin ulcers and abscesses
- Columnaris and gill disease
- Lethargy, rapid breathing, or appetite loss
Bird-Specific Symptoms Under Veterinary Guidance
- Crop infections
- Suspected salmonella or paratyphoid
- Fluffed-up feathers, lethargy, or inactivity
- Decreased appetite
- Loose or changed droppings
- Labored or difficult breathing
For birds, only use Fix Mox when an avian veterinarian has recommended amoxicillin for a specific problem. Catching an infection early, paired with clean water and good housing, gives your fish and birds the best chance to recover.
Order online and enjoy same-day dispatch on orders placed before 1:30 p.m. CT, Monday through Friday. Fix Mox ships directly from our United States warehouse via USPS or UPS.
Fish Mox vs Fix Mox: What Changed?
If you used to buy Fish Mox, Fish Mox Forte, or Aqua Mox, those brands are now discontinued or hard to find. Fix Mox from Aqua Soma Labs uses the same amoxicillin at the same strengths and steps in as a direct replacement for aquarium use.
Same Amoxicillin Inside
Fish Mox and Fix Mox both contain amoxicillin at 250 mg or 500 mg per capsule, the strengths aquarists have relied on for years.
Updated Labeling & Packaging
Fix Mox carries clear, modern labeling, with usage guidance, amoxicillin strength, and storage notes printed on the bottle.
Same Capsule Form
Pull-apart capsules dissolve in tank water, matching the format aquarists knew from Thomas Labs Fish Mox or Aqua Mox.
Fresh Stock & Current Expiration Dates
Every bottle ships with recent production and clearly printed expiration dates.
Benefits of Fix Mox for Fish & Birds
Covers Common Fish Infections
As an aquarium antibacterial treatment, amoxicillin is used against many of the bacteria behind dropsy, fin and tail rot, red streaks, gill disease, swim bladder infections, and skin ulcers in freshwater and saltwater tanks.
Handles External and Internal Problems
Use it for outward signs such as frayed fins, open sores, or red patches, and for internal infections such as hemorrhagic septicemia that bring swelling, lethargy, or appetite loss. Treat affected fish in a hospital tank.
Flexible 250 mg and 500 mg Strengths
Amoxicillin in a 500 mg or 250 mg capsule lets you scale from a small quarantine tank to a larger system. A common guide is 250 mg per 10 gallons or 500 mg per 20 gallons.
Keep a Bottle on Hand
Bacterial problems move quickly, so keeping Fix Mox stored properly means it is available at the first sign of a bacterial problem in your aquarium.
Easy to Prepare for Fish and Vet-Directed Birds
The capsules pull apart, and the contents dissolve in tank water. Under avian veterinary guidance, the contents may be mixed into soft food or water for birds with specific bacterial problems.
Built for Hospital and Quarantine Tanks
A separate treatment tank lets you remove carbon and UV, maintain stable water quality, and watch sick fish without treating healthy tank mates or sensitive invertebrates.
A Modern Swap for Discontinued Brands
When older Thomas Labs Fish Mox or Aqua Mox products are unavailable, Fix Mox provides a modern replacement with clear strength labels and fresh stock.
Usage Guidelines & Instructions
Set Up a Separate Treatment Area
Move sick fish to a dedicated hospital or quarantine tank before you dose. Take out activated carbon and switch off UV sterilizers, since both can remove amoxicillin from the water.
A 20% to 25% water change before the first dose lowers stress and starts treatment with cleaner water.
Directions for Fish Aquariums
Follow the label guide of 250 mg amoxicillin per 10 gallons or 38 litres, or 500 mg per 20 gallons or 76 litres.
Open the capsule, stir the powder into a cup of tank water, then pour it evenly around the treatment tank.
Repeat every 24 hours for 5 to 10 days, with a partial water change between doses. If nothing improves after about five days, or fish look worse, stop and ask an aquatic veterinarian.
Use in Pet Birds Under Veterinary Guidance
Use Fix Mox in pigeons and other non-food pet birds only when an avian veterinarian directs it.
The veterinarian sets the correct amount for the bird's weight, how often to give it, and how long to continue.
Capsules may be opened into soft food or drinking water so the bird receives the full intended amount, but follow the veterinarian's exact instructions rather than estimating.
Maintain Water Quality and Finish the Treatment
During treatment, monitor ammonia, nitrite, temperature, and aeration.
Finish the full treatment unless a veterinarian says otherwise. Stopping too early may allow symptoms to return.
Afterward, perform a partial water change and restore activated carbon to help remove remaining amoxicillin.
Fix Mox Amounts by Aquarium Size
| Tank volume | Amoxicillin per use | 250 mg capsules | 500 mg capsules |
|---|---|---|---|
| 10 gallons (38 L) | 250 mg | 1 capsule | Not applicable |
| 20 gallons (76 L) | 500 mg | 2 capsules | 1 capsule |
| 30 gallons (114 L) | 750 mg | 3 capsules | 1 capsule plus one 250 mg capsule |
| 40 gallons (151 L) | 1,000 mg | 4 capsules | 2 capsules |
| 55 gallons (208 L) | Approximately 1,375 mg | 5 to 6 capsules | Approximately 3 capsules |
What to Expect During Treatment
Days 1 to 2
Fish may hide or eat less, and the water may appear slightly cloudy. Keep dosing on schedule and maintain strong aeration.
Days 3 to 5
Look for sores or red patches that stop spreading, returning appetite, and steadier breathing. If there is no change by day five, or fish look worse, seek aquatic veterinary advice.
Days 5 to 10
Even when fish improve, complete the recommended treatment. After treatment, perform a partial water change and restore activated carbon.
What You Need for Treatment
A little preparation before the first dose saves trouble later.
- A separate hospital or quarantine tank so the full display aquarium is not treated
- A heater and air stone or sponge filter for stable temperature and strong aeration
- An ammonia and nitrite test kit for monitoring water quality
- A dechlorinator for water changes between doses
- A small net and clean cup for transferring fish and preparing each dose
Pro Tip: Treat sick fish in a separate hospital tank rather than the main display whenever possible. This protects the main biological filter and sensitive invertebrates while concentrating the treatment where it is needed.
How Fix Mox Works
Each Fix Mox capsule contains amoxicillin trihydrate at a strength of 250 mg or 500 mg.
Amoxicillin is an antibacterial used against many Gram-positive and some Gram-negative bacteria, including bacteria associated with fin and tail rot, skin ulcers, red streaks, and certain gill infections in ornamental fish.
Alongside the amoxicillin, each capsule contains standard ingredients that hold the capsule contents together and help them disperse properly in aquarium water or, for birds under veterinary guidance, in soft food.
Safety and Tank Notes
When used at the correct amount, Fix Mox usually causes no problems for ornamental fish or pet birds. The risk of side effects increases with excessive amounts, unnecessarily prolonged treatment, or use in an already severely stressed animal.
Unnecessary or repeated use can also contribute to antibacterial resistance.
Fish
Amoxicillin may cause temporary hiding, mild water cloudiness, or reduced appetite during treatment.
If a fish shows rapid gill movement, loss of balance, surface gasping, or remains on the bottom, stop treatment, improve aeration, add clean dechlorinated water, and contact an aquatic veterinarian.
Birds
When mixed into food or drinking water, amoxicillin may cause reduced appetite, loose or changed droppings, or lethargy, especially if the amount is too high or the bird is sensitive.
A fluffed-up or inactive bird, or one that has difficulty breathing or stops eating, should stop treatment and receive avian veterinary attention.
Invertebrates
Do not use Fix Mox in display tanks containing shrimp, snails, or other sensitive invertebrates.
Move affected fish to a separate hospital or quarantine tank whenever possible.
Safe Use in Your System
Remove activated carbon and switch off UV sterilization during treatment. Monitor ammonia, nitrite, temperature, and oxygen levels.
Do not combine Fix Mox with other treatments unless a veterinarian specifically advises it.
Important Safety & Storage Information
Fix Mox is for aquarium and ornamental fish and non-food pet birds only. It is not for animals raised for food.
If you are sensitive to penicillins, avoid direct contact with the capsule contents. Wash your hands after handling and wear suitable gloves when needed.
Store the capsules in their original container in a cool, dry location at 59–86°F or 15–30°C. Protect them from moisture and direct sunlight, keep the lid closed, and store out of reach of children and animals.

Review Refund Policy →Frequently Asked Questions
What is Fix Mox used for in fish and birds?
Fix Mox contains amoxicillin and is intended for certain bacterial problems in ornamental fish. These may include fin and tail rot, dropsy, red streaks, ulcers, abscesses, columnaris, septicemia, and certain gill infections.
For non-food pet birds, use should only occur under the guidance of an avian veterinarian.
Is Fix Mox the same as Fish Mox or Aqua Mox?
Fix Mox is presented as the current Aqua Soma Labs replacement for discontinued Fish Mox, Fish Mox Forte, and Aqua Mox products. It is available in the familiar 250 mg and 500 mg amoxicillin capsule strengths.
Is Fix Mox, also called fish mox, the same as amoxicillin?
The active ingredient in Fix Mox is amoxicillin trihydrate. Each capsule is clearly labeled as containing either 250 mg or 500 mg.
Is Fix Mox the same as fish amoxicillin 500 mg?
The 500 mg Fix Mox option contains 500 mg of amoxicillin per capsule. A separate 250 mg strength is also available.
Where can I buy Fish Mox amoxicillin online?
Fix Mox capsules can be ordered through this online store and shipped from our United States warehouse according to the current shipping terms.
Can Fix Mox be used for dogs or cats?
No. This product is labeled for ornamental aquarium fish and non-food pet birds. It is not intended for dogs, cats, humans, or food-producing animals.
What is the difference between Fish Mox and Fish Mox Forte?
The traditional Fish Mox product used the 250 mg strength, while Fish Mox Forte referred to the stronger 500 mg capsule. Fix Mox is available in both 250 mg and 500 mg strengths.
How do I know if my fish might need a fish amoxicillin treatment?
Possible bacterial signs include frayed or rotting fins, swelling, red streaks, sores, ulcers, bulging eyes, abnormal breathing, lethargy, or appetite loss.
Similar signs can also result from poor water quality, parasites, fungal problems, or other conditions, so professional assessment is recommended when the cause is uncertain.
Can I use Fix Mox in my main community or reef tank?

Fish Penicillin | Antibiotic for Aquarium Fish
Regular price $34.99 Save $-34.99Fish Penicillin 500mg | Antibiotic for Aquarium Fish
Fix Pen is an antibacterial treatment for ornamental aquarium fish and non-food pet birds.
Each tablet contains 500 mg of Penicillin V Potassium and is manufactured in the United States by Aqua Soma Labs.
Fix Pen is available in bottles containing 30 or 60 tablets with clearly printed expiration dates.
Aquarium keepers may know this product under older names such as Fish Pen, Fish Pen Forte, Aqua Pen, or FISHBIOTIC Penicillin.
These were names associated with discontinued Thomas Labs products, while Fix Pen is the current Aqua Soma Labs replacement.
Aquarium keepers may consider penicillin tablets when ornamental fish show suspected bacterial signs such as fin and tail rot, mouth rot, infected wounds, pop-eye, cloudy eyes, open sores, ulcers, reddened skin, or columnaris-type lesions with a cotton-wool appearance.
Penicillin V acts on the cell walls of certain susceptible bacteria and is generally associated with activity against Gram-positive bacteria and some Gram-negative organisms.
Fix Pen provides a consistent 500 mg tablet strength that can be dissolved in aquarium water or divided for a smaller treatment system.
The same tablets may be considered for non-food pet birds only under direct avian veterinary guidance.
Choose the 30-count bottle for a single hospital tank or occasional use, or the 60-count bottle for larger aquarium collections, multi-tank operations, or a veterinarian-directed aviary treatment plan.
Begin treatment at the first signs of a suspected bacterial concern. Symptoms differ between fish and birds, so review the separate lists below.
Fish-Specific Symptoms
- Fin and tail rot with frayed or deteriorating fins
- Mouth rot
- Infected wounds
- Pop-eye or bulging eyes
- Cloudy eyes
- Columnaris-type lesions with a cotton-wool appearance
- Open sores, ulcers, or reddened skin
- Reduced appetite, lethargy, or hiding
Bird-Specific Symptoms Under Veterinary Guidance
- Respiratory signs with labored breathing
- Soft-tissue concerns linked by a veterinarian to bacteria
- Fluffed-up feathers
- Lethargy or inactivity
- Decreased appetite
- Other symptoms specifically evaluated by an avian veterinarian
For birds, only use Fix Pen when an avian veterinarian has recommended penicillin for a specific condition and has determined the appropriate amount, administration method, frequency, and duration.
Stable water quality, appropriate nutrition, good housing, low stress, and careful observation remain essential parts of fish and bird care.
Penicillin does not treat viral problems, and unnecessary antibacterial use may reduce treatment effectiveness over time.
Same-day dispatch: In-stock orders placed before 1:30 p.m. CT, Monday through Friday, ship from our United States warehouse through USPS or UPS.
Fish Pen Forte vs Fix Pen: What Changed?
If you previously purchased Thomas Labs Fish Pen, Fish Pen Forte, Aqua Pen, or FISHBIOTIC Penicillin, here is what remains the same and what has changed.
Same Penicillin Formula
Fix Pen contains Penicillin V Potassium at 500 mg per tablet, matching the familiar strength associated with Fish Pen and Fish Pen Forte.
New Manufacturer
Fix Pen is manufactured in the United States by Aqua Soma Labs and replaces the discontinued Thomas Labs product line.
Same Dissolvable Tablet Form
The tablet can be dissolved in aquarium water or divided for smaller treatment volumes according to the current bottle label.
30-Count and 60-Count Bottles
Choose the bottle size that fits a single hospital tank, repeat treatment, multi-tank aquarium setup, or veterinarian-directed aviary plan.
Benefits of Fix Pen for Fish & Birds
Targeted Gram-Positive Bacterial Coverage
Penicillin is commonly considered when a susceptible Gram-positive bacterial component is suspected in fin damage, mouth rot, sores, ulcers, pop-eye, or cloudy eyes.
Made in the United States
Fix Pen is manufactured in the United States by Aqua Soma Labs and supplied with clearly printed strength and expiration information.
Consistent 500 mg Tablets
Each tablet provides a fixed 500 mg amount of Penicillin V Potassium, making treatment-water calculations easier across different aquarium volumes.
Common Aquarium Use Cases
Aquarium keepers may consider Fix Pen for suspected bacterial fin damage, infected wounds, flexibacter-type concerns, ulcers, and other symptoms where a susceptible bacterial cause is likely.
Freshwater and Saltwater Compatible
Fix Pen may be used in properly prepared freshwater or saltwater treatment tanks according to the current product label.
Quarantine-Friendly and Biofilter Aware
A separate hospital tank helps protect the display aquarium's beneficial bacteria, sensitive invertebrates, and healthy tank mates.
Vet-Directed Option for Pet Birds
Penicillin may be used for non-food pet birds only when an avian veterinarian has diagnosed the problem and established the appropriate treatment plan.
Usage Guidelines & Instructions
Quick Usage Summary for Fish
Use one 500 mg tablet per 20 gallons or approximately 76 litres of treatment water.
Repeat every 24 hours and perform a partial water change between treatments.
Continue for 5 to 10 days and discontinue use if no improvement is seen after five days.
Set Up a Separate Treatment Area
Treat affected fish in a hospital or quarantine tank whenever possible.
This limits exposure of healthy tank mates and makes it easier to monitor treatment response, ammonia, nitrite, temperature, and oxygen levels.
Remove activated carbon and other chemical filtration media and switch off UV sterilization during treatment.
Directions for Fish Aquariums
Dissolve one 500 mg tablet in a clean cup of aquarium water.
Add the dissolved mixture evenly throughout the treatment tank for every 20 gallons or approximately 76 litres of actual treatment water.
Calculate the real water volume after accounting for substrate, decorations, equipment, and fill level.
Repeat Every 24 Hours
Repeat treatment once every 24 hours according to the current bottle label.
Perform a partial water change between treatments to maintain suitable water quality.
Continue for 5 to 10 Days
Continue treatment for the complete recommended period, even when the fish begin to improve, unless a qualified professional advises otherwise.
Stopping treatment too early may allow the suspected bacterial problem to return.
Stop if There Is No Improvement
If no improvement is seen after five days, discontinue treatment and reassess the water quality and likely cause.
Seek aquatic veterinary or fish-health guidance if the fish become worse or develop severe distress.
Maintain Water Quality
Maintain strong aeration and stable temperature throughout treatment.
Test ammonia and nitrite regularly because antibacterial treatment may disturb beneficial filtration.
Pet Birds Under Veterinary Guidance Only
Do not use the aquarium-water chart to calculate an amount for birds.
An avian veterinarian must determine the correct amount according to species, weight, diagnosis, administration method, frequency, and duration.
Fix Pen Amounts by Aquarium Size
| Tank volume | Penicillin per use | 500 mg tablets |
|---|---|---|
| 10 gallons (38 L) | 250 mg | ½ tablet or the equivalent measured dissolved portion |
| 20 gallons (76 L) | 500 mg | 1 tablet |
| 40 gallons (151 L) | 1,000 mg | 2 tablets |
| 60 gallons (227 L) | 1,500 mg | 3 tablets |
| 75 gallons (284 L) | Approximately 1,875 mg | Approximately 4 tablets |
What to Expect During Treatment
Days 1 to 2
Fish may hide, eat less, or produce slightly cloudy treatment water. Maintain the treatment schedule and keep aeration strong.
Days 3 to 5
Look for sores and red areas that stop spreading, returning appetite, improved activity, and steadier breathing.
Days 5 to 10
Complete the recommended treatment. Afterward, perform a partial water change and restore activated carbon to help clear remaining treatment.
What You Need for Treatment
- A separate hospital or quarantine tank
- A suitable aquarium heater
- An air stone or established sponge filter
- An ammonia and nitrite test kit
- A suitable water conditioner or dechlorinator
- A small net for gentle transfer
- A clean cup for dissolving and measuring the treatment
Pro Tip: Dose according to the actual treated water volume rather than the aquarium's advertised capacity. Gravel, rocks, decorations, equipment, and the fill level reduce the amount of water inside the tank.
How Fix Pen Works
Each Fix Pen tablet contains 500 mg of Penicillin V Potassium.
Penicillin V works by interfering with the cell walls of certain susceptible bacteria.
It is generally associated with activity against certain Gram-positive bacteria and some Gram-negative organisms when used as directed in ornamental fish care.
The treatment is most appropriate when a susceptible bacterial cause is likely and should not be expected to treat fungal, viral, or parasitic conditions.
Each tablet also contains standard inactive ingredients that hold the tablet together during storage and allow it to break apart and disperse in aquarium water.
Use in non-food pet birds must follow the exact diagnosis and instructions of an avian veterinarian.
Safety and Tank Notes
When used according to the current label, Fix Pen usually causes no problems in ornamental aquarium fish.
Unnecessary use, inaccurate amounts, combining multiple treatments, or prolonged treatment may increase stress and antibacterial resistance.
Fish
Fish may temporarily hide, eat less, or appear mildly lethargic during treatment.
If severe distress develops, including rapid gill movement, surface gasping, loss of balance, rolling, or remaining on the bottom, stop treatment, increase aeration, and perform an appropriate partial water change.
Birds
Use Fix Pen in non-food pet birds only under avian veterinary guidance.
If a bird becomes unusually lethargic, stops eating, develops breathing difficulty, or appears significantly worse, discontinue use and contact the veterinarian.
Invertebrates
Do not use Fix Pen in display tanks containing shrimp, snails, corals, or other sensitive invertebrates whenever a separate treatment tank is available.
Penicillin may harm sensitive species or disturb the aquarium ecosystem.
Biofilter Awareness
Antibacterial treatment may affect beneficial filtration bacteria.
Monitor ammonia and nitrite closely and perform partial water changes whenever necessary.
Filtration During Treatment
Remove activated carbon and other chemical filtration media and switch off UV sterilization during treatment.
Restore normal filtration after treatment is complete.
Do Not Mix Treatments
Do not combine Fix Pen with other aquarium or bird treatments unless a qualified veterinarian specifically recommends the combination.
Important Safety Note
Fix Pen is intended for ornamental aquarium fish and non-food pet birds only.
It is not intended for animals raised for food.
Store tablets in their original, tightly closed container in a cool, dry place protected from direct sunlight, excessive heat, and moisture.
Keep out of reach of children and animals.
Always follow the directions printed on the current product label.

What is Fix Pen used for?
Fix Pen contains Penicillin V Potassium and is intended for certain suspected bacterial problems in ornamental aquarium fish, including fin and tail rot, mouth rot, infected wounds, ulcers, pop-eye, cloudy eyes, and some columnaris-type lesions.
Use in non-food pet birds should occur only under avian veterinary guidance.
What is the difference between Fish Pen Forte and Fix Pen?
Fix Pen is the current Aqua Soma Labs replacement for discontinued Thomas Labs Fish Pen and Fish Pen Forte products. It provides the same 500 mg Penicillin V Potassium tablet strength with updated packaging.
Is Fix Pen a replacement for FISHBIOTIC Penicillin or Aqua Pen?
Fix Pen is presented as the current replacement for older FISHBIOTIC Penicillin and Aqua Pen aquarium products.
How soon should I see improvement with Fix Pen?
Improvement may appear within three to five days through sores that stop spreading, improved appetite, increased activity, and steadier breathing.
Discontinue treatment and seek professional advice if the fish worsen or no improvement appears by day five.
Where can I buy penicillin tablets for fish online?
Fix Pen 500 mg tablets can be ordered through this online store in 30-count or 60-count bottles and shipped according to the current store shipping policy.
What is in each Fix Pen tablet?
Each tablet contains 500 mg of Penicillin V Potassium together with standard inactive tablet ingredients.
What is the Fix Pen amount for fish?
The supplied label guideline is one 500 mg tablet per 20 gallons or approximately 76 litres of treatment water.
How long should I treat with Fix Pen?
The supplied instructions describe treatment every 24 hours for 5 to 10 days, with a partial water change between treatments.
Discontinue treatment if no improvement is seen after five days.
Should I treat in the main tank or a hospital tank?
A separate hospital or quarantine tank is strongly preferred. This protects healthy tank mates, sensitive invertebrates, and the display aquarium's established filtration.
Do I need to remove activated carbon or turn off UV?
Remove activated carbon and other chemical filtration media and switch off UV sterilization during treatment because these systems may reduce treatment availability in the water.
Will Fix Pen harm beneficial aquarium bacteria?
Antibacterial treatment may disturb beneficial biological filtration. Use a separate treatment tank whenever possible and monitor ammonia and nitrite closely.
Can Fix Pen be used in saltwater aquariums?
Fix Pen is presented for properly prepared freshwater and saltwater treatment tanks. Use a separate hospital tank when the display system contains corals or sensitive invertebrates.
Is Fix Pen safe for betta fish and small aquariums?
Small aquariums require careful measurement. The supplied rate is one 500 mg tablet per 20 gallons, so a smaller treatment volume requires a proportional amount.
Dissolving one tablet in a measured volume and adding the appropriate fraction may be more accurate than dividing the tablet by hand.
Can I use Fix Pen in a planted tank or with shrimp and snails?
Treat affected fish in a separate hospital tank whenever possible. Penicillin may disturb the display aquarium and may harm shrimp, snails, or other sensitive invertebrates.
Can Fix Pen treat fungal, viral, or parasitic infections?

Perform a partial water change, resume normal filtration, restore activated carbon if normally used, and continue monitoring ammonia, nitrite, temperature, and fish behavior.
Can I use Fix Pen for dogs, cats, or chickens?
No. This product is labeled for ornamental aquarium fish and non-food pet birds. It is not intended for dogs, cats, humans, chickens raised for food, or other food-producing animals.
Can I use Fix Pen as penicillin for pet birds?
Fix Pen may be considered for non-food pet birds only under direct avian veterinary guidance. The veterinarian must establish the diagnosis, amount, administration method, frequency, and duration.
How should I store and dispose of Fix Pen tablets?
Store tablets tightly closed in their original container in a cool, dry location protected from direct sunlight, excessive heat, and moisture.
Follow the current product label and applicable local requirements when disposing of unused tablets, treatment water, or filter media. Avoid releasing concentrated treatment into natural waterways.
Bottom Line
Fix Pen is a 500 mg Penicillin V Potassium tablet for certain suspected bacterial problems in ornamental aquarium fish and a veterinarian-directed penicillin option for non-food pet birds.
It is the current Aqua Soma Labs replacement for discontinued Thomas Labs Fish Pen and Fish Pen Forte products.
The supplied aquarium guideline is one 500 mg tablet per 20 gallons or approximately 76 litres of treatment water, repeated every 24 hours for 5 to 10 days with partial water changes between treatments.
Reassess treatment at day five and discontinue use if no improvement is seen.
Fix Pen will not treat fungal, viral, or parasitic conditions and is not intended for animals raised for food.
