The Flounder (Bothus sp.) are found among the Indo-Pacific Ocean, where they hide among sand and substrate awaiting prey. They are peaceful towards other large fish, though may try to eat smaller ones. They should be kept in a fish only tank with plenty of sand to bury in. Their diets consists of small pieces of fish, mysis or krill. Flounders can reach sizes of 12+ inches, though this is less common in captivity.
