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 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.
Aulonocara stonemani is a species of haplochromine cichlid. It is endemic to the southeastern and southwestern arms of 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.
Copadichromis verduyni is a species of haplochromine cichlid which is endemic to Lake Malawi where it is found on the eastern shore and in the south eastern arm of the lake. It occurs in Malawi and Mozambique. This species inhabits the interface between sandy areas and rocky areas. Of all its congeners, this species defends the most cryptic spawning sites, these are found at depths of 9–15 metres (30–49 ft). The females and non-territorial males feed on plankton caught 1–3 metres (3.3–9.8 ft) above the lake bed and also on benthic invertebrates. Konings named this species after the Dutch cichlid dealer Dirk Verduyn (1942-2018).
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.
Diplotaxodon greenwoodi is a species of haplochromine cichlid which is endemic to Lake Malawi. It occurs in the reef and shelf zones of the lake where it preys on small cichlids. The specific name honours the English ichthyologist Peter Humphry Greenwood (1927-1995).
Lethrinops christyi is a species of cichlid endemic to Lake Malawi where it is only known from the southern part of the lake. This species grows to a length of 18.3 centimetres (7.2 in) TL. The specific name honours the collector of the type, Cuthbert Christy (1863-1932), an explorer and naturalist.
Maylandia fainzilberi is a species of cichlid endemic to Lake Malawi. It can reach a length of 12.9 centimetres (5.1 in) TL. It can also be found in the aquarium trade. The honours the tropical fish dealer Misha Fainzilber who helped the author, Wolfgang Staeck, gain access to Lake Malawi.
Mylochromis guentheri is a species of cichlid endemic to Lake Malawi where it is found over sandy substrates. This species can reach a length of 20 centimetres (7.9 in) TL. This species can also be found in the aquarium trade. The specific name honours the German-born British zoologist, ichthyologist, and herpetologist Albert Günther (1830-1914).
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.
Alticorpus geoffreyi is a species of haplochromine cichlid which is endemic to Lake Malawi, where it is widely distributed and can be found at depths of 18–150 metres (59–492 ft), although it is most common below 60 metres (200 ft). The specific name honours the British carcinologist, ecologist and ichthyologist Geoffrey Fryer, who studied the fishes of Lake Malawi, especially the cichlids which occur in the rocky areas of the lake.
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.
