Hemichromis is a genus of fishes from the cichlid family, known in the aquarium trade as jewel cichlids. Jewel cichlids are native to Africa. Within West Africa, Hemichromis species are found in creeks, streams, rivers and lakes with a variety of water qualities including brackish water lagoons.
Lamprologus is a genus of fishes from the cichlid family. They are native to Lake Tanganyika and the Congo River Basin in Africa. The type species for this genus is Lamprologus congoensis, a species from the Congo River. The genus is under some revision and may eventually be restricted to these riverine types.
Teleogramma is an African genus of cichlids with five species. These dark and slender fish barely reach 10 cm (4 in) in length and are limited to rapids in the Western Congo River basin in DR Congo/Congo Brazzaville. They are distinctive, with specialized anatomy. They are characterized by elongated heads with tubular nostrils and a lateral line that is not interrupted, as it is in most cichlids.
Thoracochromis is a fish genus of haplochromine cichlids that are endemic to Africa. Most species are from rivers in Angola and Namibia, or the Congo River Basin in Central Africa, but T. wingatii is from the Nile system. Additionally, there are a few apparently undescribed species from the Nile system, which appear to be close relatives of T. wingatii or Haplochromis loati. Many species have been moved between this genus and Haplochromis, and while some consensus has been reached in recent years, their mutual delimitation is still far from settled.
Nanochromis is a genus of small cichlids endemic to the Congo River Basin in Central Africa.
Mastacembelus is a genus of many species of spiny eel fish from the family Mastacembelidae. They are native to Africa and Asia. Most are found in rivers and associated systems, but there are also species in other freshwater habitats and a particularly rich radiation is found in the Lake Tanganyika basin with 15 species. A few species can even occur in brackish water.
Caecobarbus geertsi, the African blind barb or Congo blind barb, is a species of cyprinid fish. This threatened cavefish is only known from Democratic Republic of the Congo, and it is the only member of the monotypic genus Caecobarbus. George Albert Boulenger described this fish in 1921 and it apparently lacks any close relatives in the Congo region.
Garra is a genus of fish in the family Cyprinidae. These fish are one example of the "log suckers", sucker-mouthed barbs and other cyprinids commonly kept in aquaria to keep down algae. The doctor fish of Anatolia and the Middle East belongs in this genus. The majority of the more than 140 species of garras are native to Asia, but about one-fifth of the species are from Africa.
Raiamas is a genus of cyprinid freshwater fishes. The majority of the species are from Africa, but R. bola and R. guttatus are from South and Southeast Asia.
Marcusenius is a genus of elephantfishes native to Africa. Its members are highly diverse in size, with the smallest species reaching less than 15 cm (6 in) and the largest more than 1 m (3.3 ft).
Serranochromis is a genus of relatively large, robust cichlids from freshwater habitats in mainland Southern Africa, ranging as far north as DR Congo and Tanzania, with the highest species richness in the upper Zambezi, Okavango and Congo basins. They are typically known as largemouths or, especially among fishers, breams. Serranochromis are mostly piscivores and they are important in local fisheries.
Tylochromis is a genus of African fishes in the family Cichlidae. They are the only members of the tribe Tylochromini. Many of the species are endemic to the Congo River Basin, but species also are found in Lake Tanganyika, Cameroon, Nigeria, and West Africa from Ghana to Gambia.
Raiamas senegalensis is a species of cyprinid fish in the genus Raiamas from western Africa east to the River Nile. It sometimes is found in the aquarium trade.
Jae barb or Dja barb, Enteromius jae, is a species of cyprinid fish which like other sub-Saharan "barbs" was formerly placed in the genus Barbus, it has now been reallocated to Enteromius.
Clypeobarbus bellcrossi, the gorgeous barb, is a species of cyprinid fish native to Africa where it is found in the headwaters of the upper Zambezi River system. This species can reach a length of 9 centimetres (3.5 in) TL. It can also be found in the aquarium trade.
Petrocephalus is a genus of fish in the family Mormyridae. All the fish species of this genus are endemic to Africa.
Alestopetersius is a genus of characins, fish found mostly in Congo River Basin in Middle Africa with one species from the lower Niger River in Nigeria. There are currently 10 described species in this genus.
Eugnathichthys is a genus of distichodontid fishes found in the Congo basin in Africa. They are specialized predators that feed on the fins of other fish.
Coptodon is a genus of cichlids native to fresh, brackish and coastal marine waters in Africa with C. zillii also found in the Middle East. It is the only genus in the tribe Coptodonini. Formerly included in Tilapia, this genus and tribe was separated in 2013. Despite the change in genus, Coptodon spp. are still referred to by the common name tilapia. Several species are important in local fisheries and a few are aquacultured.
Enteromius is a genus of small to medium-sized cyprinid fish native to tropical Africa. Most species were placed in the genus Barbus.
