Product Details
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)
- Everything ships together in one box from our US warehouse
- 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
