Trochilocharax ornatus (hummingbird tetra) is a species of characin endemic to Peru. [1] This species is the only member of the genus Trochilocharax. [2]
Characiformes is an order of ray-finned fish, comprising the characins and their allies. Grouped in 18 recognized families, more than 2000 different species are described, including the well-known piranha and tetras.
Characidae, the characids or characins is a family of freshwater subtropical and tropical fish, belonging to the order Characiformes. The name "characins" is the historical one, but scientists today tend to prefer "characids" to reflect their status as a by and large monophyletic group at family rank. To arrive there, this family has undergone much systematic and taxonomic change. Among those fishes that remain in the Characidae for the time being 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 and also include popular aquarium fish species.
The black tetra, also known as the black skirt tetra, petticoat tetra, high-fin black skirt tetra, black widow tetra and blackamoor, is a freshwater fish of the characin family (Characidae). It is native to the Paraguay River basin of south-central Brazil, Paraguay and northeast Argentina, but there are also populations in the upper Paraná and Paraíba do Sul Rivers that likely were introduced. It was formerly reported from the Guapore River, but this population is part of G. flaviolimai, which is found throughout the Madeira River basin and was described in 2015. The black tetra is often kept in aquariums.
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.
Astyanax is a genus of freshwater fish in the family Characidae of the order Characiformes. Some of these fish, like many of their relatives, are kept as aquarium pets and known collectively as tetras. With around 150 described species and new ones being described yearly, this genus is among the largest of the entire order; Hyphessobrycon also has more than 145 species and which one is larger at any one time depends on whether more species have been recently described in one or the other. The blind and colorless cave tetra of Mexico is a famous member of the genus, but its taxonomic position is disputed: Some recognize it as part of the Mexican tetra and this is supported by phylogenetic evidence, but others recognize the cave form as a separate species, A. jordani.
Astyanax jordani is a freshwater fish of the characin family of order Characiformes, native to Mexico. It is sometimes called the cave tetra, or by its local Spanish name tetra ciego.
Boehlkea fredcochui, also known as the Cochu's blue tetra is a species of characin. Its natural range is in the Amazon Basin. It is commonly kept as an aquarium fish.
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).
Knodus borki is a species of characin endemic to Peru, where it is found in the vicinity of Iquitos. It is found in a freshwater environment within a benthopelagic depth range. This species is native to a tropical environment. It lives in the habitats of rivers, streams, and tributaries.
Hasemania is a genus of characins endemic to Brazil, where only found in river basins that originate on the Brazilian Shield, ranging west to the Juruena system, north to the São Francisco system and south to the Paraná system. The individual species generally have quite small ranges and two, H. crenuchoides and H. piatan, are considered threatened by Brazil's Ministry of the Environment.
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.
Hyphessobrycon bentosi, the Bentos tetra, ornate tetra or candy cane tetra, is a species of characin fish found in sluggish tributaries at the Amazon Basin in Brazil and Peru. Occasionally, it makes its way into the aquarium trade. It has often been confused with the rosy tetra.
Hyphessobrycon acaciae is a species of South American tetra fish, belonging to the family Characidae.
Hyphessobrycon agulha is a species of tetra in the family Characidae. As a freshwater fish, it inhabits the basin of the Madeira River in Brazil along with parts of Peru and Bolivia, and it reaches a maximum length of 4.3 centimetres. Though it is mainly found in the wild, it is occasionally kept by fishkeepers and is sometimes confused with the neon tetra. The fish is primarily an insectivore, though it does eat vegetable matter. It is considered to form a group with other species in Hyphessobrycon as they share a dark stripe running lengthwise.
Hyphessobrycon chiribiquete is a species of South American tetra, belonging to the family Characidae. It is green-gold in coloration. It has a black midlateral stripe running from the base of the caudal fin to the gills. The area of the caudal fin around the base in bright red in coloration, as is the anal fin. It is known to inhabit the Japurá and Ucayali River Basins. It was discovered in Chiribiquete Park in Colombia.
Hyphessobrycon clavatus is a species of South American tetra, belonging to the family Characidae. It is a pale golden green color, with its belly being even paler. It has an orange midlateral line. Below the midlateral line is a thick black stripe that fades around the gills. Their fins have white tips. They are known to reach about 3 centimeters in length. Its species name, clavatus, is derived from the Latin term clava lat, meaning club-shaped. Hyphessobrycon clavatus is known to inhabit the waters of Peru. As a pelagic fish, they swim near the surface of the water. They have seen limited use in the fish trade.
Iguanodectidae is a family of freshwater fish in the order Characiformes that lives in South America. It is home to the subfamily Iguanodectinae and the monotypic Bryconops clade. Several species in the family, such as the green line lizard tetra, the tailspot tetra, and the orangefin tetra, are sometimes taken as aquarium fish.
The tailspot tetra is a freshwater fish that lives in the coastal river regions of upper South America. Both its common and scientific names reference the distinct spot of color present on the tail fin, which is one of its defining characteristics. It is a small fish, reaching 4.8 in at its longest. Despite its small size, it is an active swimmer, with a preference for fast-flowing waters.
Bryconops piracolina is a small fish that inhabits the waters of Brazil. It is slender and silvery in color, like many fish in Bryconops, but can be distinguished from other members by way of its dorsal fin, which has a black patch of color extending up from the fin-base; congeners usually have light pigment in the dorsal fin, or a brighter color.
