Gnathochromis pfefferi is an African species of fish in the family Cichlidae. It is endemic to Lake Tanganyika and its slow-flowing tributaries in the countries of Burundi, the Democratic Republic of the Congo, Tanzania and Zambia.[1] It is common and widespread.[1] This cichlid is found in relatively shallow waters, typically over soft bottoms in places with aquatic grasses.[1]

It reaches up to 14 cm (5.5 in) in length,[2] and females are a little smaller than males.[3] It eats invertebrates (especially shrimp[4]) and plant material.[1] Like many other Tanganyika cichlids, it is a mouthbrooder[2][4] and sometimes kept in aquariums.[3]

Although currently included in the genus Gnathochromis, it is distantly related to the type species G. permaxillaris (tribe Limnochromini), instead being closer to Tropheini.[5] The specific name honours the German zoologist Georg Johann Pfeffer (1854-1931).[6]
