Carnegiella is a genus of freshwater hatchetfishes found in the Amazon and Orinoco basins in South America. This genus contains some popular aquarium fishes.
There are currently four recognized species in this genus: [1]
Anostomus is a small genus of fish in the family Anostomidae found in South America. They are found in the Orinoco and Amazon Basin, as well as various rivers in the Guianas. The genus currently contains five described species. Petulanos was until recently included here.
Argyropelecus is an oceanic ray-finned fish genus in the deep sea hatchetfish family Sternoptychidae. A collective name is "silver hatchetfishes", but this can also refer to a species of the freshwater hatchetfishes which are not particularly closely related to. The large pupils of these marine hatchetfishes enable them to see dim objects in the deep sea, where light barely penetrates.
Polyipnus is a genus of oceanic ray-finned fish in the family Sternoptychidae. This is the largest genus of the marine hatchetfishes subfamily Sternoptychinae and indeed of the entire Sternoptychidae. It is not quite as apomorphic as their relatives; it may be that the genus is actually a paraphyletic assemblage of less advanced Sternoptychinae and would need to be split.
Sternoptyx is an oceanic ray-finned fish genus which belongs in the family Sternoptychidae. This is the type genus of the Sternoptychidae, as well as the marine hatchetfish subfamily Sternoptychinae.
The freshwater hatchetfish are a family, Gasteropelecidae, of ray-finned fish from South and Central America. The common hatchetfish is the most popular member among fish keeping hobbyists. The family includes three genera: Carnegiella, Gasteropelecus, and Thoracocharax.
Serrasalmus is a genus of piranhas. They are collectively known as pirambebas; the "typical" piranhas like the piraya piranha are nowadays placed in Pygocentrus. Like all piranhas, Serrasalmus are native to South America.
Satanoperca is a small genus of cichlids from South America, where they are known from the Orinoco, Essequibo, Nickerie, Amazon and Paraná–Paraguay river basins. They are mainly found in areas with slow-moving waters, but some species have also been recorded from rapids.
Megalodoras is a small genus of thorny catfishes native to tropical South America.
Oxydoras is a genus of thorny catfishes native to tropical South America.
Amblydoras is a genus of thorny catfishes native to rivers in tropical South America.
Pterodoras is a small genus of thorny catfishes native to tropical South America.
Pimelodella is a genus of three-barbeled catfishes.
Ernstichthys is a genus of banjo catfishes that occurs in the Amazon and Orinoco basins.
The pygmy hatchetfish is a species of hatchetfish native to Peru.
The black-winged hatchetfish is a freshwater ray-finned fish native to South America.
Chaetostoma also known as the Bristlemouths is a genus of suckermouth armored catfishes native to South America with one species C. fischeri extending into Panama. Most species inhabit flowing rivers in the lower Andes and its foothills. Some species are kept in unheated aquaria.
Apteronotus is a genus of weakly electric knifefish in the family Apteronotidae, distinguished by the presence of a tiny tail fin. This genus is restricted to tropical and subtropical South America and Panama where found in a wide range of freshwater habitats. They feed on small animals.
Synaptolaemus cingulatus is a species of headstander found in Brazil and Venezuela. An examination of specimens has shown that S. cingulatus is a synonym of S. latofasciatus.
Synaptolaemus is a genus of headstanders native to South America, where found in the Orinoco, Casiquiare and Amazon Basin. Synaptolaemus are elongate in shape and overall black with contrasting red, orange or yellow stripes.
Carnegiella schereri, a species of freshwater hatchetfish, is native to the Amazon Basin in Peru and Brazil. It is often sold for the aquarium hobby under the name silver hatchetfish, dwarf hatchetfish, or Scherer's hatchetfish, and grows to about 2.6 centimeters.
