Thomas Labs Fish Flex Forte is a bacterial medication that utilizes a concentrated dose of Cephalexin, also known as Keflex, to knock out a wide range of severe bacterial infections in your aquarium fish.

  • Controls common bacterial infections in fish
  • Cephalexin dose is twice as strong as regular Fish Flex
  • Kills many pathogentic bacteria known to cause aquarium fish diseases


Fish Flex Forte is useful in controlling severe cases of a number of 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 (500 mg) into aquarium for each 20 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.

Ingredients: Cephalexin Monohydrate (500mg per capsule).

Note: For aquarium and ornamental fish only. Not for human use. Keep out of the reach of children. Keep container tightly closed and in a cool dry place. Not to be given to fish intended for food use.
