Nanochromis transvestitus is a sexually dimorphic cichlid endemic to Lake Mai-Ndombe in the Democratic Republic of the Congo where they live at a depth of around 1 metre (3.3 ft). It feeds on small benthic invertebrates. This species reaches a length of 3.4 centimetres (1.3 in) SL. Unusually for cichlids, it is the female, not the male, that is the most colourful. The female has a vertical black and white banding on her anal and caudual fins, with a bright red abdomen. The male, by contrast, is grayish in colour. Like many cichlids, the male does, however, have longer anal and caudal fins. The fish are egg layers and make a nest in the substrate in which to lay their eggs. This species is particularly threatened by the practice of using mosquito netting to catch fish out of the lake as material with holes that small catches every species of fish in the lake regardless of size. The specific name is a derived from the Latin trans meaning "cross" or "over" and vestitus meaning "clothed", a reference to the reversal of the normal sexual dimorphism in that this species has drabber males and more colourful females.
Greenwoodochromis is a small genus of cichlid fish that are endemic to Lake Tanganyika in Africa. It is the only genus in the monotypic tribe Greenwoodochromini, however, some authorities have synonymised the Greenwoodochromini with the tribe Limnochromini.
Anomalochromis is a genus of fish in the family Cichlidae, containing the single species Anomalochromis thomasi, the African butterfly cichlid. It is a small cichlid growing to a length of 6–8 centimetres (2.4–3.1 in). The natural habitat of A. thomasi is Sierra Leone, Liberia and Guinea, mainly in smaller streams. The fish are typically found in slightly acidic, oxygen rich water with other west African cichlid genera such as Hemichromis and Pelvicachromis.
The Benito is a river in Equatorial Guinea. It is known locally as the Mbini River, and, at least as it flows in its westerly part through the Monte Alen National Park, as the Uoro River. The river rises in Gabon and crosses into Equatorial Guinea where it divides the country roughly along the middle, running east to west. At the mouth to the Atlantic Ocean lies the town of Mbini, as well as large mangrove stands that extend 20 km inland. Only this 20 km portion of the river is navigable. The river is used to float logs for forestry operations. The cichlid genus Benitochromis takes the first part of its name from the Benito River.
Reganochromis calliurus is a species of cichlid endemic to Lake Tanganyika in East Africa. It lives over a sandy substrate in deeper coastal waters, to depths of at least 60 m (200 ft). Its preferred diet consists mostly of shrimp. It can reach a total length of 15 cm (5.9 in). This fish can also be found in the aquarium trade. It is currently the only known member of its genus.
Aristochromis christyi is a species of fish in the family Cichlidae, which is endemic to Lake Malawi in central Africa. It is the only known member of its genus.
The giant cichlid, also known as the emperor cichlid, is a species of fish in the family Cichlidae, endemic to Lake Tanganyika in Africa. It is the only member of its genus Boulengerochromis and tribe Boulengerochromini.
Baileychromis centropomoides is a species of cichlid endemic to Lake Tanganyika in east Africa. This fish grows to a length of 16.8 centimetres (6.6 in) TL. It is currently the only known member of its genus. The generic name is a compound noun, made up of the surname Bailey, in honour of the American ichthyologist Reeve Maclaren Bailey (1911-2011) of the University of Michigan, and the Greek word chromis which was used by Aristotle for a type of fish. This was probably the drum Sciaenidae and may be derived from the word chroemo which means "to neigh" in reference to the noise made by drums. This word was applied to a number of percomorph fishes, such as damselfish, cardinalfish, dottybacks, wrasses and cichilds, by ichthyologists as these were thought to be closely related.
Haplochromis greenwoodi is a species of cichlid endemic to Lake Victoria where they are found in the southeastern portion of the lake. Its preferred habitat consists of areas with rocky substrates. This species can reach a length of 13.5 centimetres (5.3 in) SL. The specific name honours the British ichthyologist Humphry Greenwood (1927-1995) for his contribution to the knowledge of the systematics of the Lake Victoria cichlids. This species is placed in the genus Neochromis by some authorities.
The damba is a species of cichlid.
Ptychochromis grandidieri is a species of fish in the family Cichlidae endemic to river basins along a large part of the eastern coast of Madagascar, although it has been recorded as far as 100 km (62 mi) inland. Uniquely in the genus Ptychochromis, this species also occurs in brackish water. It reaches 21.3 cm (8.4 in) in standard length. It shares a large part of its range with a cichlid from another genus, Paretroplus polyactis. The specific name honours Alfred Grandidier (1836-1921), the French naturalist and explorer who, with Henri Joseph Léon Humblot (1852-1914), collected the type.
Stigmatochromis woodi is a species of cichlid endemic to Lake Malawi where it can be found hunting for prey over sandy areas. It can reach a length of 25 centimetres (9.8 in) TL. It can also be found in the aquarium trade. The specific name honours Rodney C. Wood, whose collection of cichlids from Lake Malawi, which included the type of this species, was presented to the British Museum. It is the type species of the genus Stigmatochromis.
Chromidotilapia guntheri, or Günther's mouthbrooder, is a cichlid from Africa. It was previously considered to consist of two subspecies, the common C. g. guntheri ranges from Liberia to Equatorial Guinea and Niger, and the critically endangered C. g. loennbergi which was thought to be restricted to Lake Barombi-ba-Kotto, a small crater lake in Cameroon but these subspecies are not supported by subsequent authorities. The species is noted for being a biparental mouthbrooder. Eggs are laid on a flat open surface and taken in the parents' mouth. Unlike many mouthbrooding cichlid species, both parents participate in the mouthbrooding.
Apistogramma viejita is a dwarf cichlid in the subfamily Cichlinae, in the tribe Geophagini. It is a benthopelagic freshwater fish that lives in the Meta River and the Orinoco River in Colombia. They grow up to 4.6 cm in standard length.
Istiblennius is a genus of combtooth blennies found in the Pacific and Indian Oceans. The generic name is a compound noun composed of istio the Greek for "sail", referring to the high dorsal fin of the type species, Istiblennius muelleri, and blennius which is derived from a word for "mucus" and refers to the scaleless bodies that characterise the Blenniidae.
Rhabdoblennius is a genus of combtooth blennies found in the Pacific Ocean, mostly in the western Pacific. The name pf this genus is derived from the Greek word rhabdos meaning "stick" or "rod" and blennius meaning "mucus", referring to the absence of scales on the body of blennies.
Enigmatochromis lucanusi is a species of cichlid known only from the Foto River near Fria, Guinea.
Rondonacara hoehnei is a species of cichlid fish of the subfamily Cichlinae. This species is endemic to the upper das Mortes River basin in the Araguaia drainage of central Brazil. This species is the only known member of its genus, but it was formerly included in Aequidens. Although not yet rated by the IUCN, it has been suggested that it is seriously threatened and should be considered critically endangered. The specific name honour the collector of the type specimen, the Brazilian botanist Frederico Carlos Hoehne (1882-1959).
The bluemouth cichlid is a species of cichlid fish that is endemic to the Usumacinta River basin in southern Mexico and Guatemala. This species is the only known member of its genus.
