For ornamental aquarium fish only.
The two antibiotics every fish keeper reaches for first.
Fish Mox (amoxicillin) and Fish Ceph (cephalexin) cover the gram-positive bacteria behind most everyday tank infections. Keeping both on the shelf means you can start treatment the same day you spot torn fins or a white patch, instead of waiting three days for a delivery while the infection spreads.
What's in the pack (2 bottles):
- Fish Mox 500mg, 30 capsules (sold separately at $39.99)
- Fish Ceph 250mg, 100 capsules (sold separately at $68.99)
Use it for:
- Fin and tail rot
- Body slime and mouth fungus (columnaris-type infections)
- Cloudy eye and popeye
- Open wounds, ulcers and red sores
- Recovery after netting, shipping or fighting injuries
Why buy the pack:
- Save $18.99 versus buying the 2 bottles separately ($108.98)

- Full-size retail bottles, the same products sold individually on this site
- Sealed bottles with a long shelf life, so the pack keeps until you need it
- Free US shipping

Intended use & safety
Intended use & safety
This product is sold for use with ornamental aquarium fish only. It is not for human use, not for use in animals raised for food, and not intended for dogs, cats, livestock or any other animal.
Nothing on this page is medical or veterinary advice, and we cannot recommend doses for any animal. If a pet needs treatment, consult a licensed veterinarian who can examine the animal and prescribe appropriately.
Keep out of reach of children and pets. Store in the original sealed container in a cool, dry place away from direct sunlight. Check the lot number and expiry date printed on the packaging before use.
Antibacterial treatments can reduce the nitrifying bacteria that drive your tank's nitrogen cycle. Many aquarists treat in a separate hospital tank, monitor ammonia and nitrite during a course, and plan extra water changes afterwards.
