Thomas Labs Fish Flex is a bacterial medication that utilizes the antibiotic Cephalexin, also known as Keflex, to treat a wide range of the most common bacterial infections in your aquarium fish.
Fish Flex is useful in controlling a number of common fish infections, including fin rot, saddleback, and black patch necrosis syndromes; skin ulcers and systemic disease; may be effective against bacteria resistant to other antibiotics.
Directions: Add contents of one capsule (250 mg) into aquarium for each 10 gallons of water to be treated. Repeat in 24 hours. It is suggested that a partial water change be made between treatments. While duration of treatment depends on type and severity of infection, it is recommended that extended medication baths continue for a minimum of 5 days & for not more than 10 days. Discontinue treatment if no improvement is noted within 5 days.
