Cyprinodontiformes is an order of ray-finned fish, comprising mostly small, freshwater fish. Many popular aquarium fish, such as killifish and live-bearers, are included. They are closely related to the Atheriniformes and are occasionally included with them. A colloquial term for the order as a whole is toothcarps, though they are not actually close relatives of the true carps – the latter belong to the superorder Ostariophysi, while the toothcarps are Acanthopterygii.
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.
Rainbowfishes are small, colourful freshwater fishes belonging to the family Melanotaeniidae, found in northern and eastern Australia, New Guinea, Sulawesi and Madagascar.
The Old World silversides are a family, Atherinidae, of fish in the order Atheriniformes. Atherinidae are abundant and considered bony fish (teleost) that are widespread globally, living in rivers, estuaries, and coastal waters. They occur worldwide in tropical and temperate waters. About two-thirds of the species are marine, and the remainder live in fresh water. The 74 species are in 13 genera. The genus Craterocephalus is the most diverse with 25 species. Four genera are monotypic.
Congiopodidae, commonly known as pigfishes, horsefishes and racehorses, is a family of ray-finned fish classified with in the order Scorpaeniformes. These fishes are native to the Southern Hemisphere.
Emmelichthyidae is a small family of small to medium-sized marine ray-finned fishes known commonly as rovers, bonnetmouths or rubyfishes.
Acanthopterygii is a superorder of bony fishes in the class Actinopterygii. Members of this superorder are sometimes called ray-finned fishes for the characteristic sharp, bony rays in their fins; however this name is often given to the class Actinopterygii as a whole.
Bedotia is a genus of the family Bedotiidae of fishes endemic to Madagascar.
Bedotiinae are a subfamily of the rainbowfish family Melanotaeniidae, commonly known as the Madagascar rainbowfish, Madagascan rainbowfish, or Malagasy rainbowfish due to their endemism to Madagascar. It includes two genera, Bedotia and Rheocles.
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.
Cairnsichthys is a genus of rainbowfishes from the subfamily Melanotaeniinae. The genus is endemic to freshwater streams in eastern Queensland in north eastern Australia. The genus was designated as a monotypic genus in 1928 by John T. Nichols and Henry C. Raven but in 2018 a second species was assigned to the genus.
Rheocles derhami is a species of rainbowfish in the subfamily Bedotiinae, the Madagascar rainbowfishes. It is endemic to the Ambalona River and Mangarahar River in Madagascar. Its natural habitat is rivers. It was described by Melanie Stiassny and Damaris Rodriguez in 1992 and was named in honour of the Swiss conservationist Patrick De Rham.
Rheocles wrightae, is a species of rainbowfish in the subfamily Bedotiinae, the Madagascar rainbowfishes. It is endemic to Madagascar where its occurs in the Manambola River, near Anosibe. It is threatened by habitat loss. It was described by Melanie Stiassny in 1990 from a type locality given as "Sandrangato River, south of Moramanga".
Telmatherina antoniae is a species of fish in the subfamily Telmatherininae part of the family Melanotaeniidae, the rainbowfishes. It is endemic to Indonesia where it occurs only in Lake Matano on Sulawesi. The species was described in 1991 by Maurice Kottelat and its specific name honours his wife, Antonia.
Telmatherina opudi is a species of fish in the subfamily Telmatherininae part of the family Melanotaeniidae, the rainbowfishes. It is endemic to Indonesia. his species was described in 1991 by Maurice Kottelat from a type locality of Lake Matano. Kottelat gave the species the specific name of opudi which is the local name for all the species of Telmatherina found in Lake Matano.
Telmatherina wahjui is a species of fish in the subfamily Telmatherininae, which is part of the family Melanotaeniidae; the rainbowfishes. It is endemic to Indonesia, where it occurs only in Lake Matano on the island of Sulawesi. It can reach a maximum length of around 5 centimetres (2.0 in). This species was described in 1991 by Mairice Kottelat with a type locality of Alaponkepi which is situated at the outlet of Lake Matano. The specific name honours Beni N. Wahju who was Vice President and Secretary of P. T. Inco Industries. Mr Wahju's support was vital in ensuring that the ichthyological survey of the Malili Lakes, in which the type of this species was collected, was possible.
The surf silverside is a species of silverside from the order Atheriniformes found along the Pacific coast of Argentina and Chile. It is the only known member of its family and molecular evidence points to this species being sister to the Neotropical silversides of the family Atherinopsidae, with the Notocheiridae and the Atherinopsidae making up the suborder Atherinopsoidei. This species is characterised by the absence of a first dorsal fin. This species was described by Howard W. Clark in 1937 from types collected in the harbour of Valparaíso, Chile, and the specific name honours the American ichthyologist and authority on silversides, Carl Leavitt Hubbs (1894-1979).
Ovalentaria is a clade of ray-finned fishes within the Percomorpha, referred to as a subseries. It is made up of a group of fish families which are referred to in Fishes of the World's fifth edition as incertae sedis, as well as the orders Mugiliformes, Cichliformes, and Blenniiformes. It was named by W. L. Smith and T. J. Near in Wainwright et al. (2012) based on a molecular phylogeny, but the authors suggested that the group was united by the presence of demersal eggs that are attached to a substrate. Some authors have used the ordinal name Stiassnyiformes for a clade including Mugiloidei, Plesiopidae, Blenniiformes, Atherinomorpha, and Cichlidae, and this grouping does appear to be monophyletic.
The Atherinomorpha is a clade of fishes in the superorder Acanthopterygii, the ray-finned fishes, consisting of three orders. The clade is ranked as an infraseries within the subseries Ovalentaria, which in turn is ranked within the wider Percomorpha clade.
Atherinoidei is a suborder of the order Atheriniformes comprising six families, with a mainly Old World distribution, although a few species are found in the western Atlantic Ocean.
