Product Details

Fix Mox (Amoxicillin) 250mg & 500mg Capsules

Fix Mox (Amoxicillin) delivers targeted broad-spectrum antibiotic care for ornamental marine and freshwater fish. Designed to tackle common bacterial infections in aquarium environments, it helps control pathogenic spread to keep your aquatic setup thriving. The pure amoxicillin formulation dissolves into the tank water to treat systemic and external bacterial issues without unnecessary fillers.

Features and Benefits

Broad-Spectrum Antibacterial Action: Effectively targets gram-positive and select gram-negative bacteria to help control common aquarium bacterial diseases.
Multiple Strength Options: Available in 250 mg and 500 mg capsule options to allow precise dosing for varying aquarium sizes.
Pure Active Ingredient: Formulated with pure amoxicillin and no artificial dyes or unnecessary chemical fillers.
Multi-Condition Relief: Helps control bacterial infections associated with fin rot, pop-eye, columnaris, gill disease, and skin ulcerations.

Usage Guidelines & Instructions −

1. Quarantine Setup & Water Preparation Isolate affected fish in a separate hospital tank prior to medication. Discontinue chemical filtration (activated carbon) and turn off UV sterilizers during administration, as these remove active amoxicillin from the solution. Performing a partial water change beforehand minimizes organic waste and reduces environmental stress.

2. Aquarium Dosing Instructions Administer 250 mg of amoxicillin per 10 gallons (38 L) or 500 mg per 20 gallons (76 L) of aquarium water. Separate the capsule halves, pre-dissolve the powder in a small container of aquarium water, and distribute evenly across the water surface. Repeat the dose every 24 hours for a duration of 5 to 10 days. Conduct a partial water change between consecutive treatments. If no clinical improvement is observed within 5 days, halt treatment and consult a licensed veterinarian.

3. Administration in Non-Food Avian Species Fix Mox may be administered to non-food pet birds (such as pigeons) strictly under the direct supervision and dosage regimen prescribed by a licensed avian veterinarian. Capsules are typically opened and thoroughly incorporated into soft food or dissolved in fresh drinking water to ensure complete delivery. Follow veterinary orders exclusively regarding dosage, administration frequency, and total treatment duration.

4. Water Quality Management & Post-Treatment Care Maintain high aeration and closely monitor essential parameters, including ammonia and nitrite, throughout the medication regimen. Complete the full course of therapy to prevent antibiotic resistance or symptom relapse. Upon completion, perform a partial water change and reintroduce activated carbon filtration to remove residual medication and clear any temporary yellow water discoloration.

How Fix Mox Works +

Fix Mox contains amoxicillin, a broad-spectrum antibiotic that exerts bactericidal action against gram-positive and certain gram-negative bacteria.

By disrupting bacterial cell growth in the aquatic environment, it halts the multiplication of susceptible pathogens responsible for common ornamental fish illnesses.

Safety and Tank Notes +

Caution: Keep out of reach of children. Fix Antibiotics are for aquarium use only. Intended for ornamental fish and/or ornamental organisms, and not intended for use with fish that are intended for human consumption.

Broad-spectrum antibiotics can affect beneficial biofilter bacteria. Treating in a dedicated quarantine tank is suggested. If treating the main tank, check water parameters such as ammonia and nitrite daily.

Storage: Keep lid tightly fastened and store at controlled room temperature of 59°–86°F (15°–30°C).

Fish Mox vs Fix Mox: What Changed? +

If you previously relied on legacy brands like Thomas Labs Fish Mox, Fish Mox Forte, or Aqua Mox, those specific labels are discontinued or scarce. Fix Mox from SourceMax Labs serves as a direct alternative, offering the same active ingredient and strength profiles for ornamental aquatic husbandry.

Identical Active Amoxicillin Fix Mox provides the exact pharmaceutical-grade amoxicillin (250 mg or 500 mg per capsule) trusted by hobbyists for years.

Updated Labeling & Compliance Features clear, modern labeling produced by SourceMax Labs with explicit dosing instructions, active concentrations, and storage notes.

Matching Pull-Apart Capsules Uses standard pull-apart capsules designed to dissolve smoothly in tank water, maintaining the familiar administration format.

Fresh Inventory & Dating Sourced directly from current production lots with clearly stamped expiration dates for reliable potency.

Frequently Asked Questions

Do I need a prescription from a veterinarian to purchase Fix Mox? +

No prescription is required. Fix Mox is an over-the-counter antibiotic formulated specifically for ornamental fish and aquarium husbandry.

What specific bacterial conditions does amoxicillin treat in ornamental fish? +

It treats bacterial infections including fin and tail rot, pop-eye, columnaris disease, skin ulcerations, and infected gills.

Can Fix Mox be taken by humans or administered to mammalian pets like dogs or cats? +

No. This product is strictly formulated, labeled, and sold for ornamental fish and non-food organisms. It must never be consumed by humans or given to mammals.

Will dosing Fix Mox disrupt the biological filter in my aquarium? +

Because amoxicillin is a broad-spectrum antibiotic, it can affect beneficial nitrifying bacteria in your filter media. Dosing in a dedicated hospital or quarantine tank is strongly recommended to protect your main aquarium's biofilter.

How should I prepare the capsules before adding them to the tank? +

Separate the capsule halves, pour the dry powder into a cup of warm tank water, stir thoroughly until fully mixed, and distribute the mixture evenly across the water surface.

Why does the aquarium water turn slightly yellow during treatment? +

Amoxicillin can impart a harmless yellow tint to the water. To clear the water after treatment, perform a 20% partial water change and run activated carbon in your filtration system until clear.

How long should an extended treatment bath last? +

Extended medication baths should run for a minimum of 5 days and a maximum of 10 days. Discontinue treatment if no noticeable improvement occurs within 5 days.
