Labeotropheus are easily distinguished from other mbuna genera by their curved, hanging snout. This special adaptation allows them to graze on rocks on an almost parallel plane, letting them feed on rocks that other fish may not be able to reach. Male Katale Island may be solid blue or OB patterned. Females are OB.
