Fish Mox 500mg Capsules contains amoxicillin, a penicillin-class (aminopenicillin) antibiotic. Amoxicillin is a beta-lactam antibiotic that kills bacteria by blocking construction of their cell walls. It is one of the most commonly used antibiotics in the aquarium hobby.

Spectrum: Mainly gram-positive bacteria, plus some gram-negative species. It is not active against parasites, viruses or fungi.

What it is commonly used for

Aquarists and keepers commonly turn to this ingredient for:

  • Fin rot and tail rot
  • Bacterial ulcers and body wounds
  • Mouth and skin infections
  • Secondary infections after injury or handling

Things to know before you treat

  • Beta-lactams can be broken down by some resistant bacteria; if a fish does not improve, a different class is usually the next step.
  • People with a penicillin allergy should avoid handling the capsules or treated water without gloves.
  • Antibiotics can harm the beneficial bacteria in a biofilter, so treating in a hospital tank protects the main aquarium.

Fish Mox 500mg Capsules FAQ

What is amoxicillin used for in fish?

Aquarists commonly use amoxicillin for bacterial problems such as fin rot, ulcers and skin infections. It only works on bacteria, so it will not help with parasites like ich or with true fungal infections.

Is Fish Mox the same as human amoxicillin?

Fish Mox contains the same active ingredient, amoxicillin, but it is labeled and sold for ornamental aquarium fish only. It is not intended for human use or for fish raised for food.

Should I use 250mg or 500mg capsules?

The strength is a packaging choice. Larger systems use more medication, so many keepers pick the 500mg size to reduce the number of capsules to handle. Always follow the directions printed on the product you receive.

Is Fish Mox 500mg Capsules for humans?

No. It is labeled for ornamental aquarium fish only and is not for human use or for fish intended for food. Keep out of reach of children.

Is shipping really free?

Yes. Shipping is free to any US address, and tracking is emailed when your order ships.

How do I pay?

Checkout accepts credit and debit cards, Apple Pay and Google Pay through Airwallex's secure payment page.
