Alticorpus peterdaviesi is a species of fish in the family Cichlidae. It is endemic to Lake Malawi. It is found in the southern part of the lake, in areas where the substrate consists of "diatom ooze" and diatoms probably form the major part of its diet.
The nkhomo-benga peacock, also known as the new yellow regal peacock, is a species of haplochromine cichlid which is endemic to Lake Malawi. This species is threatened by capture for the aquarium trade.
The Chitande aulonocara is a species of haplochromine cichlid which is endemic to Lake Malawi, only occurring in the north-west of the Lake near Chitande Island. It occurs over habitats of mixed rock and sand and it feeds on benthic invertebrates. The males show territorial behaviour all year and defend their territories from other males. These territorial males are found in deeper areas around 15 metres (49 ft) while the non territorial males and the females are rarely seen below 3 metres (9.8 ft). Ripe females descend towards the males and spawning takes place in a cavity or, if the male's territory does not include a cavity, on the open sand. The specific name honours the British ichthyologist Ethelwynn Trewavas (1900-1993) of the British Museum who described a number of species of cichlid from Lake Malawi.
Aulonocara gertrudae is a species of haplochromine cichlid which is endemic to Lake Malawi, being found in Malawi, Mozambique, and Tanzania. The habitat varies between populations, those south of the Ruhuhu River are sand dwellers which exploit the sandy muddy substrates found near river mouths, while those to the north of the Ruhuhu will occupy rocky habitats too. This is thought to be cause there are fewer rock inhabiting congeners north of the Ruhuhu. The territorial males of this species excavate a burrow in the sand or they may use a cavity formed in a rocky area, especially in the northern populations. The females are found in small foraging groups in the vicinity of the males. The specific name honours Konings' wife, Gertrude Dubin.
Aulonocara guentheri is a species of haplochromine cichlid endemic to Lake Malawi, where they are restricted to the south eastern arm, and Lake Malombe, meaning that as far as is known this fish is endemic to Malawi. It prefers shallow sandy habitat where it forages in small schools, males in breeding colours have been caught by fishermen in November and December suggesting that is when they breed. The specific name honours the German born British herpetologist and ichthyologist Albert Günther (1830-1914), who was one of the first scientists to recognise the diversity of te cichlids in Lake Malawi.
Aulonocara korneliae, known in the aquarium fish trade as the Aulonocara Chizumulu, Aulonocara blue gold or blue orchard Aulanocara, is a species of haplochromine cichlid.
The sulfurhead aulonocara or sulfurhead peacock is a species of haplochromine cichlid which is endemic to Lake Malawi in the country of Malawi and has only been observed on West Reef and Eccles Reef. It is threatened by collection for the aquarium trade and this has caused a 70% reduction in numbers. In this mouthbrooding species, the eggs are cared for by the females only, and it is found over mixed sand and rocky areas where they hunt small invertebrates in the sand. It closely resembles the blue orchid aulonocara though it develops a yellow blaze across its dorsal In the past these two taxa have been considered to be subspecies. The specific name honours Hans-Joachim Mayland, an author on cichlids and a fishkeeper, brought the species to the attention of Ethelwynn Trewavas.
The greenface aulonocara is a species of haplochromine cichlid which is endemic to Lake Malawi.
The flavescent peacock, also known as Grant's peacock, is a species of haplochromine cichlid. Its common name refers to its "flavescent" (yellowish) colour.
Diplotaxodon ecclesi is a species of haplochromine cichlid. It is endemic to Lake Malawi where it is found in open water at mainly at the deeper levels, although it is rarely caught by trawling. Its main prey is the Lake Malawi sardine.
Astatotilapia tweddlei is a species of fish in the family Cichlidae. It is found in Malawi and Mozambique. Its natural habitats are rivers and freshwater lakes.
Labidochromis freibergi is a species of cichlid endemic to Lake Malawi where it is only known to occur around Likoma Island in areas with rocky substrates. This species grows to a length of 8 centimetres (3.1 in) TL. The specific name of this species honours the American fish importer Jacob Freiberg.
Lethrinops stridei is a species of cichlid endemic to Lake Malawi where it occurs at depths of from 15 to 55 metres in areas with sandy substrates. This species grows to a length of 13 centimetres (5.1 in) SL. The specific name honours Kenneth E. Stride, who introduced successful commercial trawling to Lake Malawi, and this species is now very rare in Lake Malawi and is threatened by overfishing by commercial trawlers.
Livingston's bulldog Marcusenius livingstonii is a species of ray-finned fish in the family Mormyridae. It is found in Malawi, Mozambique, and Tanzania. Its natural habitats are rivers, intermittent rivers, and freshwater lakes. It is threatened by habitat loss.
Maylandia livingstonii is a species of cichlid native to Lake Malawi and Lake Malombe. This species can reach a length of 15 centimetres (5.9 in) TL. It can also be found in the aquarium trade. The specific name of this fish honours the Scottish explorer and missionary David Livingstone (1813-1873).
Placidochromis hennydaviesae is a species of cichlid endemic to Lake Malawi where it is only known from the southern portions of the lake. It is found in areas with muddy substrates at depths of from 71 to 100 metres. This species can reach a length of 10 centimetres (3.9 in) TL.
Aulonocara jacobfreibergi, the eureka red peacock, is a species of fish in the family Cichlidae. It is also known as Freiberg's peacock or fairy cichlid. There are several colour morphs including red or yellow. They generally can grow to around 15 cm in length.
Aulonocara koningsi is a species of haplochromine cichlid which is endemic to Lake Malawi. It is restricted to the waters around Mbenji Island and is therefore endemic to Malawi too. It is common in the restricted area in which it occurs but collection for the aquarium trade does not seem to have affected the population.
Maylandia flavifemina is a species of haplochromine cichlid which is endemic to Lake Malawi.
