Paratilapia polleni is a medium-sized cichlid endemic to Madagascar. It is also a popular fish for display at public aquaria.
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.
Neolamprologus wauthioni is a species of cichlid endemic to Lake Tanganyika where it inhabits snail shells. This species reaches a length of 5.5 centimetres (2.2 in) TL. The specific name of this cichlid honours René Wauthion, a Provincial Commissioner in the Belgian Congo during the Belgian Hydrobiological Mission to Lake Tanganyika of 1946–1947, this expedition collected the type.
Oxylapia is a genus of freshwater fish in the family Cichlidae. It contains the single species Oxylapia polli, known locally as the songatana. It is an endangered species, endemic to the Marolambo Rapids in the Nosivolo River in east-central Madagascar. It is threatened by habitat loss and sedimentation caused by deforestation. The only other monotypic cichlid genus in Madagascar is Katria, and it is restricted to the same region as Oxylapia. In 2010, the Nosivolo River was designated as a Ramsar Site. The Oxylapia is the conservation flagship species for the district capital Marolambo.
Paretroplus dambabe is an endangered species of cichlid from the Mahavavy du Sud river basin, including Lake Kinkony, in northwestern Madagascar. It has declined drastically due to habitat loss, invasive species and over-fishing. This relatively large and deep-bodied Paretroplus reaches almost 19 centimetres (7.5 in) in length. Although collected as early as the 1960s, it was long confused with P. petiti and therefore only described as a species in 2002.
Paretroplus is a genus of fishes in the cichlid family, all of which are endemic to lakes and rivers of Madagascar. The vast majority are threatened and restricted to the northwestern part of the island. Only P. polyactis is found in the southern half of Madagascar and only P. polyactis and P. gymnopreopercularis are found in eastern drainages. Most are restricted to freshwater, but at least P. polyactis and P. maromandia can also be seen in brackish habitats.
The damba is a species of cichlid.
The kotsovato is a species of cichlid from northwestern Madagascar. As presently defined its range spans several river basins, but this could possibly include more than one species. It is threatened by habitat loss and competition from introduced species. This relatively elongate Paretroplus reaches about 16 centimetres (6.3 in) in length and is closely related to P. gymnopreopercularis, which it resembles. The specific name honours the French fisheries scientist André Kiener.
The damba mipentina is a critically endangered species of cichlid fish from turbid, shallow flood-plain lakes in the Betsiboka and Ikopa River basins in northwestern Madagascar. It has declined drastically because of habitat loss, overfishing and invasive species. It is part of a captive breeding program by public institutions like London Zoo and among fishkeeping hobbyists.
Paretroplus maromandia is an endangered species of cichlid fish from fresh and brackish water in northwestern Madagascar, where known from the Maintsomalaza, Andranomalaza and Maevarano Rivers, and Lake Andrapongy. It has already been extirpated from the lake, and is threatened by habitat loss and invasive species. This relatively deep-bodied Paretroplus reaches 25 centimetres (9.8 in) in length.
Paretroplus nourissati, the lamena, is a species of cichlid from the vicinity of the confluence of the Amboaboa and Mangarahara Rivers near Mandritsara in northern Madagascar. This relatively elongate Paretroplus reaches about 16 centimetres (6.3 in) in length, and is closely related to P. lamenabe and P.tsimoly. P. nourissati is threatened by habitat loss and invasive species.
Paretroplus polyactis is a vulnerable species of cichlid found widely in fresh and brackish water in coastal regions and associated river basins in eastern Madagascar. It is the only Paretroplus found in the southern half of Madagascar, and one of only two found in eastern drainages. P. polyactis is threatened by habitat loss and overfishing. This relatively deep-bodied Paretroplus reaches 30 centimetres (12 in) in length. It shares a large part of its range with a cichlid from another genus, Ptychochromis grandidieri.
Paretroplus gymnopreopercularis is a species of cichlid from the vicinity of the confluence of the Amboaboa and Mangarahara Rivers near Mandritsara in northern Madagascar. Until its official scientific description in 2008, it was temporarily known as the Paretroplus nov. sp. "sofia". It is endangered because of habitat degradation, overfishing and invasive species. Following the construction of a dam on the Mangarahara River, surveys have failed to relocate P. gymnopreopercularis in this river.
Paretroplus tsimoly is a species of cichlid fish from the Betsiboka River basin in northwestern Madagascar. Like other members of the lamena group, it is a rheophile. This relatively elongate Paretroplus reaches about 16 centimetres (6.3 in) in length, and is closely related to P. lamenabe and P. nourissati.
Placidochromis johnstoni is a species of cichlid native to Lake Malawi, Lake Malombe and the upper reaches of the Shire River where it prefers shallow waters with plentiful vegetation. This species can reach a length of 20 centimetres (7.9 in) TL. It can also be found in the aquarium trade. The specific name honours the British explorer, botanist, artist, colonial administrator and linguist Sir Henry Hamilton Johnston, better known as Harry Johnston, who collected the type and sent it to the British Museum.
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 35cm 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.
Ptychochromis loisellei is a species of cichlid from the Mahanara River basin north of Sambava in northeastern Madagascar. It remains common within its small range, but it is threatened by habitat loss and introduced species. It reaches about 11.9 centimetres (4.7 in). The similar named Paretroplus loisellei is also restricted to the Mahanara River basin. The specific name honours Paul V. Loiselle, Emeritus Curator of Freshwater Fishes at the New York Aquarium and a researcher in, and campaigner for the conservation of, the freshwater fish of Madagascar.
Ptychochromis ernestmagnusi is a species of fish cichlid only known from the Mananara du Nord River in northeastern Madagascar, but it is probably more widespread in that region. If so, it likely occurs in the Mananara-Nord Biosphere Reserve, which would give it a level of protection. It can reach 14.7 cm (5.8 in) in standard length. The specific name honours Ernest Magnus (1908-1983) who was the uncle of the German-American marine biologist and ichthyologist Rudolf Arndt who gave generous support to the author's research, at the request of Anrdt's family, whose “generous gift” supported the authors’ research. Magnus played an important part in assisting the Arndt family to survive in Berlin after the Second World War and then emigrate to New York City in 1950, by giving them "food, clothing, shelter, love, many kindnesses and moral support".
Paretroplus loisellei is a vulnerable species of cichlid fish from the Mahanara River basin north of Sambava in northeastern Madagascar. Until its scientific description in 2011, this population was usually referred to as Paretroplus sp. nov. "Ventitry" or included in P. damii, which it resembles. It reaches about 15 centimetres (5.9 in) in length, and is threatened by habitat loss and introduced species. The similar named Ptychochromis loisellei is also restricted to the Mahanara River basin. The specific name honours Paul V. Loiselle, Emeritus Curator of Freshwater Fishes at the New York Aquarium and a researcher in, and campaigner for the conservation of, the freshwater fish of Madagascar.
Biotodoma wavrini,(Orinoco eartheater), is a species of cichlid in the tribe Geophagini, part of the American cichlid subfamily Cichlinae. It is found in the middle and upper Rio Negro drainage in Brazil and Venezuela, and in the Orinoco River basin in Colombia and Venezuela. Its specific name honours the Belgian aristocrat, ethnologist and explorer Marquis Robert de Wavrin de Villers-au-Tertre (1888–1971), who collected the type specimen in 1935. B. wavrini is around 10 cm in length. The Orinoco eartheater poses no threats to humans.
