Amphilophus labiatus is a large cichlid fish endemic to Lake Managua and Lake Nicaragua in Central America. In the aquarium trade A. labiatus is often sold under the trade name of red devil, a common name which they share with Amphilophus citrinellus.
Colouration in wild specimens is variable and while most specimens are grey to greyish green some pink, red or white specimens do occur. Black pigmentation in spots or bands is also common. Some specimens have enlarged lips, though this condition is thought to be related to specific food choice preferences in their natural habitat as this trait disappears in captivity. Like most cichlids, A. labiatus has advanced brood care. The species forms monogamous pairs which spawn on flattened rocks or logs.
Aquarists who keep cichlids regard red devils as aggressive fish. This aggressive behavior combined with their razor sharp teeth and powerful jaws means cohabitants should be chosen carefully and the fish should be kept in a large aquarium. Red Devils may be so aggressive that they ram into the glass to get at invaders, break heaters and other aquarium equipment, and will sometimes bite their owners.
