Characidae, the characids or characins, is a family of freshwater subtropical and tropical fish belonging to the order Characiformes. The name "characins" is a historical one, but scientists today tend to prefer "characids" to reflect their status as a, by and large, monophyletic group. To arrive there, this family has undergone much systematic and taxonomic change. Among those fishes remaining in the Characidae currently are the tetras, comprising the very similar genera Hemigrammus and Hyphessobrycon, as well as a few related forms, such as the cave and neon tetras. Fish of this family are important as food in several regions, and also constitute a large percentage of captive freshwater aquarium fish species.
Hyphessobrycon is a genus of freshwater fish in the family Characidae. These species are among the fishes known as tetras. The genus is distributed in the Neotropical realm from southern Mexico to Río de la Plata in Argentina. Many of these species are native to South America; about six species are from Central America and a single species, H. compressus is from southern Mexico.
Pristella is a genus of fish in the family Characidae. It was formerly a monotypic taxon only containing Pristella maxillaris, but in 2019 a second species, Pristella ariporo, was described.
Bryconops is a genus of freshwater fish in the family Iguanodectidae from South America. It consists of small fish, all under half-a-foot long, with slender bodies and silvery scales, though there is some mild color variation. Several species can be identified by way of a humeral patch, and others have a reddish ocellus, or eyespot, on one or both lobes of the dorsal fin.
Moenkhausia is a genus of freshwater fish in the family Characidae native to tropical and subtropical South America. These are medium-sized tetras where the largest species only reach around 12 cm (4.7 in).
Ctenobrycon is a genus of fish of the family Characidae found in tropical South America, with five currently recognized species in this genus. Ctenobrycon species can be located is fresh water in tropical climates in South America, commonly in calm waters. Their diet includes zooplankton, plants, worms, insects, and crustaceans.
Ctenobrycon spilurus, the silver tetra, is a species of tropical freshwater fish sometime referred to as the silver dollar tetra. It is a member of the family Characidae in the order Characiformes. The fish is native to the Orinoco River basin and coastal river basins of Guyana, Suriname and French Guiana, as well as Brazil and Venezuela, and can be found in shallow slow moving streams with heavy vegetation. With temperatures that range from 23–27 °C (73–81 °F). The fish can grow to a maximum length of 8.0 cm.
Salminus, popularly known as dorado or dourado, is a genus of relatively large, predatory freshwater fish from the family Characidae. They are native to large tropical and subtropical rivers in South America, and undertake migrations during the rainy season to spawn. They are very popular among recreational anglers and also support important commercial fisheries.
Chrysobrycon is a genus of characins endemic to South America.
Gymnocorymbus is a genus of small characins from the Amazon, Paraguay, Orinoco, Courantyne, Gurupí and Parnaíba river basins in South America. These tetras are popular in the aquarium trade.
Hemigrammus is a genus of freshwater fish in the family Characidae native to South America and commonly seen in the aquarium trade. These are medium-small tetras where the largest species reach up to around 11 cm (4.3 in).
Tyttocharax is a genus of characins found in tropical South America.
Carlastyanax aurocaudatus is a small species of freshwater fish in the family Characidae native to the Río Cauca in Colombia. It is the only member of the monotypic genus Carlastyanax, which was named in 1972 specifically for the species by Jacques Géry. Upon description, it was named Astyanax aurocaudatus by Carl H. Eigenmann. There has been debate concerning whether or not the genus should be recognized, but C. aurocaudatus is currently considered a valid species.
Hyphessobrycon acaciae is a species of South American tetra fish, belonging to the family Characidae.
Bryconops alburnoides is a small freshwater fish, approximately 6 inches long at its largest, that lives in the rivers of South America. It has a slender body, with a yellowish dorsal fin and yellow-tinged back scales that fade into silver on its belly. It is largely an insectivore that picks land-dwelling insects from the riverbanks, though it eats much more whenever rain washes prey into the water.
Pristella crinogi is a freshwater fish in the family Characidae of the order Characiformes. It is a tropical fish. It resides in the basins of the Tocantins River and São Francisco River.
Bryconops giacopinii is a mid-sized species of freshwater fish in the family Iguanodectidae. It is the largest member of the genus Bryconops, and is therefore difficult to confuse with any of its congeners. With a diet that consists largely of land-dwelling insects, it serves as an important link between the terrestrial and aquatic aspects of its native range.
Bryconops humeralis is a small freshwater fish distributed across northern South America. The name "humeralis" means "relating to the shoulder", in reference to the distinct humeral patches that the fish sports. It is slightly longer than average in terms of the genus Bryconops, though still firmly within the standard range, and is slightly more slender than is usual for its congeners.
Bryconops vibex is a small freshwater fish from the rivers of Venezuela, known solely from the Rio Cataniapo. The body is slender, though with an element of sturdiness, and it has one humeral spot by each pectoral fin. It bears visual similarities to several congeners, but can be differentiated by way of many factors.
Tyttocharax metae is a small freshwater fish of the family Characidae which is found in the Güejar river system of the Orinoco Basin in Colombia. It was discovered in the Columbian municipality of Vista Hermosa in 2009 and was formally described in 2012 by Román-Valencia, García-Alzate, Ruiz-C. & Taphorn.
