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.
The threadfin rainbowfish or featherfin rainbowfish is a rainbowfish, the only species in the genus Iriatherina. It is characterized by long beautiful fins, and is among the most attractive of the rainbowfishes.

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 red-tailed silverside, or zona is a species of Madagascar rainbowfish endemic to the Mananjary River drainage in Madagascar. It is threatened by habitat loss and introduced species. It has often been confused with the related B. madagascariensis, which is common in the aquarium trade. In addition to meristics, the two can be separated by the exact colour pattern on their tail fin and the distinct red spot on the lower jaw of breeding male B. geayi. B. geayi was described in 1907 by Jacques Pellegrin from a type collected by the pharmacist and natural history collector Martin François Geay (1859-1910), who Pellegrin honoured with its specific name.
Axelrod's rainbowfish is a species of rainbowfish in the subfamily Melanotaeniinae. It is found in Papua New Guinea in the Yungkiri stream in the north western part of that nation. Typically its preferred habitat is a narrow stream with gentle moving, cloudy water surrounded by lush rainforest.
Astatotilapia flaviijosephi, the Jordan mouthbrooder, is a vulnerable species of freshwater fish in the family Cichlidae (cichlids). It is found in the central Jordan River system, including Lake Tiberias (Kinneret), in Israel, Jordan and Syria, making it the only haplochromine cichlid to naturally range outside of Africa. This species is too small to be of significant importance to fisheries, unlike the only other cichlids native to the Levant, the economically important tilapias.
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.
Ogilby's rainbowfish is a species of rainbowfish in the subfamily Melanotaeniinae. It is endemic to West Papua in Indonesia in the Lorentz River system. This species was described in 1910 by Max C.W. Weber from types collected in the Noord-Fluss, now renamed the Lorentz River, by the Dutch explorer Hendrikus Albertus Lorentz in 1907, it was not recorded again until Gerald R. Allen collected more specimens in 1995 and the species was later introduced to the aquarium hobby. Its specific name honours the ichthyologist James Douglas Ogilby (1853-1925).
The Popondetta blue-eye or Popondetta rainbowfish, is a species of fish in the subfamily Pseudomugilinae. It is endemic to Papua New Guinea where it occurs at three localities around Popondetta in the east of the country. This species inhabits clear, fast flowing freshwater streams, although it has been reported from brackish water. This species was described in 1981 as Popondetta connieae by Gerald R. Allen from a typelocality of Auga Creek, about 5 kilometres (3.1 mi) south of Popondetta where Allen collected the 200 types along with Brian Parkinson. Allen gave it the specific name connieae to honour his wife, Connie, who normally prepared Allen's manuscripts for publication. This species is sought-after in the aquarium trade and is available in the European and Australian markets.
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.
Chrysiptera starcki is a species of damselfish known by the common name Starck's demoiselle. It is native to the western Pacific Ocean, where it has been reported from the Ryukyu Islands and Taiwan to Australia, New Caledonia, and Tonga. It was originally described in 1973 as Abudefduf starcki.
