Mbuna is the common name for a large group of African cichlids from Lake Malawi, and are members of the haplochromine family. The name mbuna means "rockfish" in the language of the Tonga people of Malawi. As the name implies, most mbuna are cichlids that live among the piles of rocks and along the rocky shores of Lake Malawi, as opposed to the utaka, cichlids that live in the open water or on sandy shores or soft substrates. Some species of mbuna are highly sexually dimorphic, although many are not. Among biologists, almost all of the cichlid species of Lake Malawi, including mbuna and non mbuna such as the utaka, are believed to have descended from one or a very few species that became isolated in the lake. With rising water levels, new habitats could be colonized and the many isolated rocky outcrops allowed new mbuna species to form. Their striking colors, intriguing behavioral characteristics, and relative hardiness make them very popular despite their unique demands for the home aquarist.
Pseudotropheus is a genus of fishes in the family Cichlidae. These mbuna cichlids are endemic to Lake Malawi in Eastern Africa.
Aulonocara is a genus of haplochromine cichlids endemic to Lake Malawi in East Africa. All Aulonocara species are maternal mouth brooders. Particularly in the aquarium hobby, Aulonocara species are also known as peacock cichlids, aulonocaras or simply "peacocks". This genus is strongly sexually dichromic, even by haplochromine standards.
Maylandia or Metriaclima is a genus of haplochromine cichlids endemic to Lake Malawi in East Africa. They belong to the mbuna (rock-dwelling) haplochromines.
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.
Dr. Ethelwynn Trewavas was an ichthyologist at the British Museum of Natural History. She was known for her work on the families Cichlidae and Sciaenidae. She worked with Charles Tate Regan, another ichthyologist and taxonomist.
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.
Corematodus is a small genus of haplochromine cichlids native to the Lake Malawi basin in Africa. They feed on scales and fins of other cichlids.
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.
Buccochromis is a genus of relatively large haplochromine cichlids endemic to Lake Malawi and the upper Shire River in East Africa.
Otopharynx is a genus of haplochromine cichlids endemic to Lake Malawi in Eastern Africa.
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.
Copadichromis borleyi is a species of haplochromine cichlid fish endemic to Lake Malawi in East Africa. The species is popular in the fishkeeping hobby where it is frequently kept in aquariums. The species has numerous common names, including redfin hap and goldfin hap.
Copadichromis trewavasae is a species of haplochromine cichlid which is endemic to Lake Malawi. It is widespread in the Lake, and so occurs in Malawi, Mozambique, and Tanzania. It is often found in areas rich in sediment where muddy deposits cover the underlying substrate, It feeds by picking out particles from the water column. This species of Copadichromis is named after noted ichthyologist Ethelwynn Trewavas.
Copadichromis virginalis is a species of haplochromine cichlid, which is endemic to Lake Malawi the upper Shire River and to Lake Malombe. It is found in Malawi, Mozambique, and Tanzania. The population has shown signs of a severe decline and is under pressure from overfishing for food, in 2018 this led to the IUCN changing its status from Data Deficient to Near Threatened.
Mylochromis is a genus of haplochromine cichlids endemic to Lake Malawi in Eastern Africa.
Nyassachromis is a genus of haplochromine cichlids endemic to Lake Malawi. They are open-water mouthbrooders, an ecological niche known as utaka to locals.
Petrotilapia is a genus of cichlids endemic to Lake Malawi.
Stigmatochromis is a small genus of haplochromine cichlids that are endemic to Lake Malawi in East Africa.
Tropheops is a genus of cichlids endemic to Lake Malawi.
