Sarotherodon is a genus of tilapiine cichlids endemic to Africa and the Middle East. A few species from this genus have been introduced far outside their native range, and are important in aquaculture. They mainly inhabit fresh and brackish water, but a few can live in salt water. Members of this genus, as well as those of the genera Tilapia and Oreochromis, share the common name "tilapia".
Nimbochromis is a small genus of haplochromine cichlids mostly endemic to Lake Malawi in East Africa. They are known as sleeper cichlids or kaligono due to their unique hunting behaviour.
Buccochromis is a genus of relatively large haplochromine cichlids endemic to Lake Malawi and the upper Shire River in East Africa.
Champsochromis is a small genus of cichlid fishes endemic to Lake Malawi in east Africa.
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.
Astroblepus is a genus of fish in the family Astroblepidae found in South America and Panama. This genus is the only member of its family. These catfishes are primarily found in torrential streams in the Andean area. Astroblepus pholeter and A. riberae are troglobites adapted to living in subterranean water systems. These species are typically small, less than 10 cm (4 in). The largest species reaches 30 cm (1 ft). These fish have suckermouths like those of loricariids. They have two pairs of barbels, maxillary and nasal. The dorsal fin spine lacks a locking mechanism. These fish also have odontodes, tiny teeth on their skin. All species exhibit a conical, pointy type on their fin rays like that found in other loricarioids; other species also exhibit a blunt type that is only found on their skin.
Leptobarbus is a genus of cyprinid fish that are native to freshwater habitats in Southeast Asia. They are important food fish. It is the only genus in the subfamily Leptobarbinae.
Synodontis is the largest genus of mochokid catfishes. It is the biggest genus within the 10 genera and 190 different species in the family Mochokidae. Synodontis has over 131 different species within the genera. Synodontis are also known as squeakers, due to their ability to make stridulatory sounds through their pectoral fin spines when handled or disturbed. Synodontis make a sound that sounds like squeaking by rubbing their spines together. They do this when they have been frightened or when they become angry. "Synodontis" may also squeak when they are taken out of the water. These catfish are small- to medium-sized fish with many species exhibiting attractive spotted markings. Some species are also known for naturally swimming belly-up, earning the name upside-down catfish. Some of these species are Synodontis contractus and Synodontis nigriventris. While some of these species are known to swim upside down, another species, Synodontis multipunctatus, is a brood parasitic cuckoo catfish.
Rhamphochromis is a genus of East African haplochromine cichlids endemic to the Lake Malawi basin, including the main lake, Lake Malombe, Lake Chilingali, Chia Lagoon and upper Shire River. They mainly occur in offshore open waters, but a few species also near the coast. They are piscivores that typically feed on lake sardines and small utaka cichlids.

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.
Chaetostoma also known as the Bristlemouths is a genus of suckermouth armored catfishes native to South America with one species C. fischeri extending into Panama. Most species inhabit flowing rivers in the lower Andes and its foothills. Some species are kept in unheated aquaria.
