Lake Nyasa is noted for being the site of evolutionary radiations among several groups of animals, most notably cichlid fish. In total there are about 1,000 cichlid species in Lake Nyasa and the vast majority are endemic. Many of these have become popular among aquarium owners due to their bright colors. Recreating a Lake Nyasa biotope to host cichlids became quite popular in the aquarium hobby. The cichlids of the lake are divided into two basic groups, loosely referred to as the haplochromines and the tilapiines. Within the first group, Haplochrominae, there are two subgroups. The first one consists of open water and sand dwelling species whose males display bright colors and whose females show a silvery coloration with sometimes irregular black bars or other markings. The second subgroup is known both locally and popularly as mbuna, which means "rockdwellers". The Mbuna species tend to be smaller, often specialized aufwuchs feeders, and often both sexes are brightly colored with males having several egg shaped gold spots on their anal fin. All haplochromines from Lake Malawi are mouthbrooders.
The second group, the tilapiines, comprises the only substrate-spawning species in the lake (Coptodon rendalli), in addition to the five mouthbrooding species of chambo (Nyasalapia, a subgenus of Oreochromis).
