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]

<i>Ectodus</i> Species of fish

Ectodus descampsii is a species of cichlid fish endemic to Lake Tanganyika in East Africa where it prefers areas with substrates of coarse sand. It feeds on micro-organisms, algae and diatoms.

<i>Neolamprologus leleupi</i> Species of fish

Neolamprologus leleupi is a species of cichlid endemic to Lake Tanganyika where it occurs throughout the lake. It is a recess-dweller, inhabiting cracks and crevices. It feeds on invertebrates living in the rich biocover of the substrate. This species reaches a length of 10 centimetres (3.9 in) TL. The color of this fish ranges from bright yellow to deep brown. Both color variations exist at each location where this species is found. This relatively small cichlid is a substrate spawner. It is easily confused with the very similar N. longior a fish also endemic to Lake Tanganyika. The specific name honours the Belgian entomologist Narcisse Leleup (1912-2001), who collected the type.

<i>Grammatotria</i> Genus of fishes

It is currently the only known member of its genus. The species is occasionally kept as an aquarium fish. The specific name honours Lieutenant Charles Lemaire (1863-1925) who was the leader of the Congo Free State Expedition, which collected specimens of fishes at Lake Tanganyika, including the type of G. lemairii.

Giant cichlid Species of fish

Baileychromis centropomoides is a species of cichlid endemic to Lake Tanganyika in east Africa. This fish grows to a length of 16.8 centimetres (6.6 in) TL. It is currently the only known member of its genus. The generic name is a compound noun, made up of the surname Bailey, in honour of the American ichthyologist Reeve Maclaren Bailey (1911-2011) of the University of Michigan, and the Greek word chromis which was used by Aristotle for a type of fish. This was probably the drum Sciaenidae and may be derived from the word chroemo which means "to neigh" in reference to the noise made by drums. This word was applied to a number of percomorph fishes, such as damselfish, cardinalfish, dottybacks, wrasses and cichilds, by ichthyologists as these were thought to be closely related.
