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 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.
The night aulonocara is a species of freshwater fish in the family Cichlidae. It is endemic to Lake Malawi and known from the Malawian part of the lake. It grows to 7.9 cm (3.1 in) SL. The specific name honours the cichlid aquarist Eberhard Hüser of Hildesheim in Germany.
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.
Buccochromis rhoadesii is a species of haplochromine cichlid. It is endemic to Lake Malawi, Lake Malombe and the upper Shire River in the countries of Malawi, Mozambique, and Tanzania.
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 ichthyologist Karel F. Liem (1935-2009), in recognition of his studies of cichlids.
Copadichromis geertsi is a species of haplochromine cichlid which is endemic to Lake Malawi.
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).
Gephyrochromis lawsi is a species of haplochromine cichlid which is endemic to the northern part of Lake Malawi in Malawi and Tanzania. This species is normally found at deep levels where the steep, rocky coastlines meet sand substrates where it prefers patches of sand at average depths of around 20 metres (66 ft). They feed mainly on loose aufwuchs. The males are weakly territorial and will defend their territories against intruderswhile the females are solitary. It may be threatened by overfishing by fishermen using beach seine nets, although it is a bycatch rather than one of the target species, it is sometimes collected for the aquarium trade. The specific name honours the Scottish missionary Robert Laws (1851-1934).
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.
The Pearl of Likoma is a species of fish in the family Cichlidae endemic to Lake Malawi where it is native to rocky areas around Likoma Island and it has been introduced to Thumbi West Island. This species can reach a length of 10 centimetres (3.9 in) TL. It can also be found in the aquarium trade. Males are blue, while females are a greenish blue with rows of yellowish spots and shiny gills. They feed on crustaceans, insects, and larvae.
Nimbochromis linni is a species of cichlid endemic to Lake Malawi where it prefers areas with rocky substrates, though it occasionally enters intermediate habitats. This species can reach a length of 25 centimetres (9.8 in) TL. It can also be found in the aquarium trade. The specific name honours D. Wayne Linn of the Fisheries Office in Malawi, whose help to Herbert R. Axelrod made his field trip to Lake Malawi possible.
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.
