Nimbochromis livingstonii, Livingston's cichlid or (locally) kalingono, is a freshwater mouthbrooding cichlid native to Lake Malawi, an African Rift Lake. It is also found in the upper Shire River and Lake Malombe. They are found in inshore areas of the lake over sandy substrates. [2]
A laterally compressed fish with a large mouth. Maximum reported length of male fish in the wild is 25 centimetres (9.8 in) TL while females reach 20 centimetres (7.9 in) TL. [2] Colouration variable but typically mottled brown and white. The dorsal fin may also show blue coloration while maintaining an orange to red band and sometimes a white line. Adult males frequently "color up" in response to changing conditions and rapidly change from spotted camouflage to brilliant blues and greens and may even exhibit a pale golden tone. Breeding males turn a dark blue which almost completely obscures their blotched pattern. The anal fin is usually orange to red. Females are similar, but usually lack the yellow "egg spot" markings on the anal fin. Juveniles display a brown and white spotted pattern.
The distinctive colouration of this species is said to mimic that of a dead fish, and may be part of a hunting strategy.
Wild fish feed primarily on small fish, in particular Lethrinops spp. Aquarium specimens have been observed to lie on the substrate as if dead, waiting for small fish to come close in search of a meal. When a suitable target comes into range, the fish quickly lunges at the prey and usually swallows it whole. [3] It is this unique hunting method that gives the fish its local name, kalingono, which means "sleeper". [4]
Males are polygamous and will mate with multiple females. This species is a mouthbrooder with the female incubating up to 100 eggs until they hatch and the fry become free swimming, [4] much like the Astatotilapia burtoni which is of the same tribe.
Nimbochromis livingstonii is used locally as a food fish and is also collected and traded as an aquarium fish.
The identity of the person honoured in the specific name is not given in Günther's description but it is thought likely to be the Scottish missionary and explorer Dr. David Livingstone (1813-1873) who was the first known European to discover Lake Malawi in 1856, collecting the first specimens of fishes from the Lake.

Maylandia estherae is a haplochromine cichlid. It is a rock dwelling fish or mbuna from Lake Malawi. This fish, like most cichlids from Lake Malawi, is a mouthbrooder - females hold their fertilized eggs then fry in their mouths until they are released after about 21 days.
Maylandia lombardoi, is a 13 centimetres (5.1 in) long freshwater fish from the family Cichlidae. This species is popular in the aquarium hobby where it is sold under a variety of common names including: lombardoi mbuna, kenyi mbuna or kennyi mbuna or kenyi cichlid. This species is sometimes seen in the genus Metriaclima owing to a dispute in which a minority of cichlid researchers do not consider Maylandia valid (see Maylandia for discussion. The specific name honours the exotic fish dealer John Lombardo.
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).
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 venustus, commonly called venustus hap or giraffe hap, is a Haplochromine cichlid endemid 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.
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.
Copadichromis borleyi is a species of haplochromine cichlid fish endemic to Lake Malawi in East Africa. The species is popular in the fishkeeping hobby where it is frequently kept in aquariums. The species has numerous common names, including redfin hap and goldfin hap.
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.
Copadichromis geertsi is a species of haplochromine cichlid which is endemic to Lake Malawi.
Iodotropheus stuartgranti is a species of cichlid endemic to Lake Malawi. It can also be found in the aquarium trade. This species can reach a length of 10 centimetres (3.9 in) TL. The specific name honours Stuart M. Grant (1937-2007), an exporter of cichlids from lake Malawi for the aquarium trade. This species feeds maonly on aufwuchs. The males are territorial and the female will lay anywhere within a male's territory.
The convict julie is a cichlid species in the subfamily Pseudocrenilabrinae family endemic to Lake Tanganyika. Hence it is found in Burundi, the Democratic Republic of the Congo, Tanzania, and Zambia. The fish is named after Charles Tate Regan.

Pseudotropheus saulosi is a species of cichlid endemic to Lake Malawi in East Africa where it lives in areas with rocky substrates. It is classified as a dwarf-mbuna and was first described by Ad Konings in 1990 who gave it the specific name saulosi in honour of Saulos Mwale who caught over 3,000 specimens in a single day on the expedition which collected the type. It comes from an area of the lake called Taiwan Reef, and from nowhere else. This fish can also be found in the aquarium trade.
Tilapia sparrmanii, the banded tilapia, or vlei kurper, is a widespread and adaptable cichlid fish that is found in warmer freshwater habitats of southern Africa. They prefer water with ample plant cover, and occur naturally as far north as DR Congo and Tanzania. They have been introduced locally in the northern hemisphere. Younger banded tilapia feed on crustaceans and insect larvae, while the adults feed on terrestrial and aquatic plants and other debris. They undertake local migrations and may shoal before and during spawning time. They guard their own eggs, and although they may move eggs or fry in the mouth, they are not known to be actual mouthbrooders like several other tilapia species. This species can reach a length of 23.5 centimetres (9.3 in) TL and is an important foodfish.
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.
