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.
Aulonocara aquilonium is a species of fish in the family Cichlidae. It is endemic to Malawi. Its natural habitat is freshwater lakes where it occurs in areas of sandy substrate where mature males defend a small territory of sand against other mature males of this species. The foraging females and non-breeding males form large schools. It is found at depths ranging from 12–25 metres (39–82 ft). During the months of November and December A. aquilonium is abundant where there is an interface between rock and sandy habitats near Mdoka on the northwestern shores of Lake Malawi
Aulonocara auditor is a species of haplochromine cichlid endemic to Lake Malawi. It was known only from the holotype collected in northern Lake Malawi near Vua, Malawi. The IUCN state that this species may possibly be extinct due to beach seining within its limited range but there are claims that it was observed in 1989 and was quite numerous, although this was later retracted and it was stated that these observations referred to Aulonocara aquilonium. Following an examination of the holotype, this examination also suggests that A. auditor may not be a species of Aulonocara and that more material needs to be collected and studied.
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.
Aulonocara brevinidus is a species of haplochromine Cichlid it is endemic to Lake Malawi and widespread along the eastern shore of the lake. It is found in Malawi, Mozambique, and Tanzania. In this species the males defend small territories over sandy areas at depths of 20 metres (66 ft) where the excavate shallow nests, in denser populations these territories may be as little as 2 metres (6.6 ft) apart. The diet appears to consist of small invertebrates.
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.
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.
Aulonocara rostratum is a species of haplochromine cichlid. It is endemic to Lake Malawi where it is found in Malawi and Tanzania. It is found throughout the lake. The males gather in loose aggregations in sandy areas, defending small territories which they defend from other males.
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 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).
Eclectochromis lobochilus is a species of fish in the family Cichlidae. It is found in Malawi, Mozambique, and Tanzania. Its endemic to Lake Malawi.
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).
Limnotilapia dardennii, the latticed cichlid, is a species of cichlid endemic to Lake Tanganyika, where it prefers rocky areas near the coast. It may also be found in the aquarium trade. This species is currently the only known member of its genus.
The Gulf grouper is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is endemic to Mexico.
Aulonocara nyassae, known as the emperor cichlid, is a species of haplochromine Cichlid that is endemic to Lake Malawi in Africa. It has been recorded from the southeastern arm of the lake and may be present in the southwestern arm. This species was known only from its holotype, which was collected at the turn of the century, until more specimens were collected in the 1990s.
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.
