Antibiotic Duo Flake – Bacterial Treatment Food for Ornamental Aquarium Fish

Antibiotic Duo Flake combines two treatment compounds commonly used by aquarists when managing bacterial issues affecting ornamental aquarium fish. Using more than one treatment compound can provide broader coverage when the exact cause of symptoms is uncertain.

Because this treatment is delivered through food, fish are able to receive the treatment internally while continuing to feed normally. The highly palatable flake formulation helps ensure fish continue eating during the treatment period.

Safe for use in aquariums containing invertebrates when used as directed.
