Nimbochromis venustus, commonly called venustus hap or giraffe hap, is a Haplochromine cichlid endemic to Lake Malawi in Africa. It prefers the deeper regions of the lake where it hunts smaller juvenile cichlids with a specialised hunting technique. After spotting prey, it will partially submerge itself into the sand and lie motionless until the chosen fish comes within reach. it will then dart out of the sand and strike. It is related to Nimbochromis livingstonii. In the wild it is known to grow to 25 centimetres (9.8 in) TL though usually not exceeding a length of 22.5 centimetres (8.9 in) TL.

Chalinochromis brichardi is a species of fish in the family Cichlidae. It is found in Burundi, the Democratic Republic of the Congo, Tanzania, and Zambia. It is endemic to Lake Tanganyika. It builds a nest of rubble which is hidden by plants or algae, and its diet consists primarily of invertebrates.

Caprichromis liemi, the happy, is a species of haplochromine cichlid. It is endemic to the Lake Malawi region, being also found in Lake Malombe and the upper Shire River. It occurs over sandy substrates but it frequently remains in midwater. This species is a specialised predator, a paedophage, which steals the broods from mouthbrooding female cichlids by ramming the brooding female's head from below. Examination of their stomach contents resulted in the recovery of eggs, larvae and fry only. The juveniles act a cleaner fish, and so may the adults. The males build "sand castle" spawning sites. The specific name honours the Indonesian ichthyologist Karel F. Liem (1935–2009), in recognition of his studies of cichlids.
