Fish Antibiotics
All of the medicines we carry are NON-PRESCRIPTION fish antibiotics. They are the same USP grade antibiotics produced by pharmaceutical companies that also produce antibiotics for human use. Every capsule or tablet is labeled, imprinted, and often color-coded with a special code that can be used to identify the strength and type of the antibiotic by performing an internet search. The Dosages and Strengths and medications are for use in ornamental or pet fish only.
Fish Mox, Fish Flex, Fish Zole, Fish Cillin, Fish Flox, Fish Cycline
