The myaka (Myaka myaka) is a critically endangered species of cichlid endemic to Lake Barombi Mbo in western Cameroon. It prefers open, deeper waters where it feeds on phytoplankton and small insects, only venturing into shallower waters to spawn. This species can reach a length of SL. It is currently the only known species in the genus Myaka, but it is very close to Sarotherodon. The myaka is threatened because of pollution and sedimentation due to human activities. It is potentially also threatened by large emissions of carbon dioxide (CO2) from the lake's bottom (compare Lake Nyos), althoug

Nimbochromis is a genus of haplochromine cichlids mostly endemic to Lake Malawi in East Africa. They are known as sleeper cichlids or kaligono ("sleepers" in Chichewa) due to their unique hunting behaviour: these piscivorous species are often seen lying motionless on the lake bottom near rocks where mbuna live, even adopting an unusual sideways position rarely seen in living fish. When smaller fish approach, the Nimbochromis will "wake up" and try to seize them from ambush. Their coloration has an irregular dark cloudy pattern on lighter background (giving them their generic name) which provid

Placidochromis is a genus of cichlids endemic to Lake Malawi in Eastern Africa. They are part of the haplochromine lineage of Lake Malawi's cichlid taxa. Most Placidochromis species live in the open or sandy regions of the lake.

Copadichromis is a genus of haplochromine cichlids endemic to Lake Malawi in Eastern Africa. Copadichromis are part of a group known as utaka and are popular with aquarists, as this genus is relatively peaceful in captivity compared to the mbuna.

Aristochromis christyi is a species of fish in the family Cichlidae, which is endemic to Lake Malawi in Africa. It is the only known member of its genus.

Melanochromis is a genus of haplochromine cichlids endemic to Lake Malawi in Eastern Africa. Ecologically, they belong to the rock-dwelling mbuna cichlids of Lake Malawi.

Chetia is a genus of haplochromine cichlids endemic to riverine habitats in southern Africa, as well as the Congo River Basin.

Nyassachromis is a genus of haplochromine cichlids endemic to Lake Malawi. They are open-water mouthbrooders, an ecological niche known as utaka to locals.

Dimidiochromis is a genus of haplochromine cichlids endemic to Lake Malawi in East Africa. All of its species are elongated in shape and predatory on smaller fishes.

Sciaenochromis is a genus of haplochromine cichlids endemic to Lake Malawi in East Africa. The species are popular in the aquarium hobby, most notably S. fryeri.

Protomelas is a genus of haplochromine cichlids endemic to Lake Malawi in East Africa. The genus is part of the haplochromine tribe and have maternal mouthbrooding and sexual dimorphism typical of this group. Popular in the aquarium hobby, Protomelas species are sold under a variety of trade names (e.g., Taiwan Reef Cichlid, Red Empress Cichlid).

Taeniolethrinops is a small genus of haplochromine cichlids endemic to Lake Malawi.

Tyrannochromis is a small genus of haplochromine cichlids endemic to Lake Malawi.

Tristramella is a genus of oreochromines, freshwater fishes in the cichlid family. The members of this genus prefer standing waters and their native range is restricted to the Jordan River system, including Lake Tiberias (Kinneret), in Israel and Syria, with introduced populations in a few other places in Syria. Its members are among the few cichlids native to Western Asia, the others being Astatotilapia flaviijosephi, Coptodon zillii, Iranocichla, Oreochromis aureus, O. niloticus and Sarotherodon galilaeus.

Stigmatochromis is a small genus of haplochromine cichlids that are endemic to Lake Malawi in East Africa.

Petrotilapia is a genus of cichlids endemic to Lake Malawi.

Buccochromis is a genus of relatively large haplochromine cichlids endemic to Lake Malawi and the upper Shire River in East Africa.

Greenwoodochromis is a small genus of cichlid fish that are endemic to Lake Tanganyika in Africa. It is the only genus in the monotypic tribe Greenwoodochromini, however, some authorities have synonymised the Greenwoodochromini with the tribe Limnochromini.

Trematocranus is a small genus of haplochromine cichlids endemic to Lake Malawi.

Caprichromis is a small genus of haplochromine cichlids endemic to Lake Malawi in East Africa. This genus contains noted paedophagous cichlids, specialising in the eating of eggs and fry of other cichlid species.

Stomatepia is a genus of cichlids endemic to Lake Barombi Mbo in western Cameroon. Although generally recognized as distinct, the genus is very close to Sarotherodon. The Stomatepia species are all recognized as critically endangered by the IUCN because of pollution and sedimentation due to human activities. They are potentially also threatened by large emissions of carbon dioxide (CO2) from the lake's bottom (compare Lake Nyos), although studies indicate that Barombo Mbo lacks excess amounts of this gas. Konia, Myaka and Pungu are three other equally threatened genera of cichlids that also ar

Ctenopharynx is a small genus of haplochromine cichlids from East Africa. Two of its species are endemic to Lake Malawi, while the third occurs in Lake Malawi and the upper reaches of the Shire River.

Eclectochromis is a small genus of haplochromine cichlids endemic to Lake Malawi.

Diplotaxodon is a small genus of seven formally described, as well as a number of undescribed, deep-water species of cichlid fish endemic to Lake Malawi in east Africa. These fishes represent a remarkable adaptive radiation of offshore and deep-water adapted fish descended from ancestral shallow water forms. They include the dominant zooplankton-feeding fish of the offshore and deep-water regions of the lake, as well as a number of larger species that appear to feed on small pelagic fishes. Adult sizes range from 10 to 30 cm in total length, depending on species.
