For the stubborn infections amoxicillin does not touch.

Fish Flox (ciprofloxacin) and Fish Dox (doxycycline) are the go-to pair for gram-negative bacteria, the aggressive kind that causes bleeding, ulcers and organ damage. When a fish is bloating, showing red veins or losing tissue, this is the pack you want already in the cabinet.

What's in the pack (2 bottles):

Fish Flox 500mg, 30 tablets (sold separately at $69.99)
Fish Dox 100mg, 30 tablets (sold separately at $49.99)

Use it for:

Red streaks in fins and body (hemorrhagic septicemia)
Ulcers and open sores that keep growing
Dropsy-type bloating and pinecone scales
Aeromonas and Pseudomonas infections
Mouth rot and gill infections

Why buy the pack:

Save $19.99 versus buying the 2 bottles separately ($119.98)
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
