Nyassachromis prostoma is a species of fish in the family Cichlidae. It is endemic to Lake Malawi and found in Malawi and Tanzania. [2]
Lake Malawi, also known as Lake Nyasa in Tanzania and Lago Niassa in Mozambique, is an African Great Lake and the southernmost lake in the East African Rift system, located between Malawi, Mozambique and Tanzania.
Cheilochromis is a genus of freshwater fish in the cichlid family. It contains the sole species Cheilochromis euchilus, the Malawi thicklip, which is endemic to Lake Malawi in East Africa where it prefers near-shore areas with rocky bottoms. This species reaches a length of 35 centimetres (14 in) TL. It can also be found in the aquarium trade.
The haplochromine cichlids are a tribe of cichlids in subfamily Pseudocrenilabrinae called Haplochromini. This group includes the type genus (Haplochromis) plus a number of closely related genera such as Aulonocara, Astatotilapia, and Chilotilapia. They are endemic to eastern, southern and northern Africa, except for Astatotilapia flaviijosephi in the Middle East. A common name in a scientific context is East African cichlids – while they are not restricted to that region, they are the dominant Cichlidae there. This tribe was extensively studied by Ethelwynn Trewavas, who made major reviews in 1935 and 1989, at the beginning and at the end of her career in ichthyology. Even today, numerous new species are being described each year.
Cyrtocara moorii, commonly known as the hump-head, is a species of haplochromine cichlid endemic to Lake Malawi in east Africa where they prefer areas with sandy substrates. It can grow to a length of 20 centimetres (7.9 in) TL. The species is popular among aquarium keepers where it is known as the hump-head cichlid, blue dolphin cichlid, Malawi dolphin or simply as moorii. It is currently the only known member of its genus. The specific name honours the English cytologist and biologist John Edmund Sharrock Moore (1870-1947).
Melanochromis auratus, the auratus cichlid, is a freshwater fish of the cichlid family. It is also known as golden mbuna and Malawi golden cichlid. It is endemic to the southern region of Lake Malawi, particularly from Jalo Reef southward along the entire western coast down to Crocodile Rocks.
Pseudotropheus crabro, the Bumblebee Cichlid or Hornet Cichlid, is a species of cichlid endemic to Lake Malawi where it is found in different habitats but most frequently in large caves or in the vicinity of large boulders. This species can reach a length of 16 centimetres (6.3 in) SL.
Iodotropheus sprengerae, the rusty cichlid, lavender mbuna or lavender cichlid, is a species of cichlid endemic to the Boadzulu and Chinyankwazi Islands and Chinyamwezi Island regions of Lake Malawi. It prefers a temperature range of 24-26 °C.
Nimbochromis polystigma is a species of cichlid endemic to Lake Malawi, in the Great Rift Valley system of Africa. This species prefers areas with rock/sand substrate or areas with plentiful vegetation. It can grow to a length of 23 centimetres (9.1 in) TL.
Aristochromis christyi is a species of fish in the family Cichlidae, which is endemic to Lake Malawi in Africa. It is the only known member of its genus.
Nyassachromis boadzulu is a species of haplochromine cichlid. It is endemic to Lake Malawi where it occurs off Boadzulu Island and White Rock in the south-eastern arm of the lake.
Labidochromis mathotho is a species of cichlid endemic to Lake Malawi. This species grows to a length of 8 centimetres (3.1 in) TL.
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.
Melanochromis loriae is a species of cichlid in the Cichlidae endemic to Lake Malawi. This species can reach a length of 12.5 centimetres (4.9 in) TL.
Nyassachromis breviceps is a species of cichlid endemic to Lake Malawi where it is only found in the southern part of the lake. It prefers areas with sandy substrates but needs a supply of small pebbles for nest building. This species can reach a length of 15.4 centimetres (6.1 in) TL. This species was last observed in Lake Malawi in 1997 and is thought that it may be extinct, caused by overexploitation by artisanal fishermen.
Nyassachromis is a genus of haplochromine cichlids endemic to Lake Malawi. They are open-water mouthbrooders, an ecological niche known as utaka to locals.
The small green utaka is a species of cichlid endemic to Lake Malawi where it prefers areas with a sandy substrate. This species can reach a length of 16 centimetres (6.3 in) TL. It can also be found in the aquarium trade.
Nyassachromis nigritaeniatus is a species of cichlid endemic to Lake Malawi where it prefers areas with sandy substrates. This species can reach a length of 21 centimetres (8.3 in) TL. It can also be found in the aquarium trade.
Nyassachromis purpurans is a species of cichlid endemic to Lake Malawi where it prefers areas with sandy substrates. This species can reach a length of 18 centimetres (7.1 in) TL. It can also be found in the aquarium trade.
Nyassachromis serenus is a species of cichlid endemic to Lake Malawi where it is only known from the northern part of the lake, preferring habitats over sand-rock interfaces. This species can reach a length of 25 centimetres (9.8 in) TL. It can also be found in the aquarium trade.
The Super VC-10 hap is a species of cichlid endemic to Lake Malawi along the Malawian shores of the lake. It prefers areas with rocky substrates. This species can reach a length of 18.7 centimetres (7.4 in) SL. It can also be found in the aquarium trade. In the wild uses its thickened lips to scrape algae from rocks and this seems to thicken the lips further, which tends not to be the case with aquarium specimens which have only slightly thickened lips.
