Most Groupers grow up to 12 inches in captivity and frequently outgrow the average-sized aquarium. The diet of these fish consists of fish, crustaceans, and cephalopods. A large aquarium with adequate hiding places is necessary to maintain Groupers in captivity. It is advisable to keep one species of Grouper per tank, as these fish may become aggressive towards other tankmates and themselves.
