Labeotropheus
Labeotropheus is a small genus of cichlid fish endemic to Lake Malawi in eastern Africa. It includes at least two species, each with a number of subspecies or races. Further taxonomic work is required to determine how many species exist. These cichlids are popular ornamental fish and are ideally suited to the cichlid aquarium. Like many Malawi cichlids, Labeotropheus species are algal grazers.
