Fish Flex 250 mg 100 Capsules – Cephalexin Fish Antibiotics for Aquarium Use

Fish Flex 250 mg Capsules contain Cephalexin Monohydrate 250 mg, a broad-spectrum antibiotic formulated to treat bacterial infections in ornamental and aquarium fish. The 250 mg strength provides greater dosing flexibility for smaller aquariums, sensitive species, and controlled bacterial treatment programs in both freshwater and saltwater systems.

Cephalexin is a first-generation cephalosporin antibiotic that works by interfering with bacterial cell wall synthesis, preventing bacterial growth and limiting infection spread within the aquarium. It is commonly used in cases where fish exhibit symptoms consistent with gram-positive and certain gram-negative bacterial infections.

Important: For aquarium use only. Not for human consumption. Not for fish intended for human consumption.
