Phenacogrammus is a genus of African tetras found in Middle Africa.
There are currently 10 recognized species in this genus: [1]
Tetra is the common name of many small freshwater characiform fishes. Tetras come from Africa, Central America, and South America, belonging to the biological family Characidae and to its former subfamilies Alestidae and Lebiasinidae. The Characidae are distinguished from other fish by the presence of a small adipose fin between the dorsal and caudal fins. Many of these, such as the neon tetra, are brightly colored and easy to keep in captivity. Consequently, they are extremely popular for home aquaria.
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.
The Congo tetra is a species of fish in the African tetra family, found in the central Congo River Basin in Africa. It is commonly kept in aquaria.
African tetras are a group of characiform fish exclusively found in Africa. This family contains about 18 genera and 119 species. Among the best known members are the Congo tetra, and African tigerfish.
Maylandia or Metriaclima is a genus of haplochromine cichlids endemic to Lake Malawi in East Africa. They belong to the mbuna (rock-dwelling) haplochromines.
Copella is a genus of freshwater fish belonging to the family Lebiasinidae, native to South America, known colloquially to aquarists as splashing tetras or splash tetras, because of the unique reproductive method of the best-known representative of the genus, Copella arnoldi. They are not as closely related to the tetras proper in the Characidae as initially believed.
Brycinus is a genus of ray-finned fish in the family Alestiidae. Like other "African characids", they were formerly included in the Characidae but are actually somewhat more distantly related Characiformes.
Micralestes is a genus of African tetras. There are currently 17 species in this genus.
Paramormyrops is a genus of elephantfish in the family Mormyridae from Africa.
Alestopetersius is a genus of characins, fish found mostly in Congo River Basin in Middle Africa with one species from the lower Niger River in Nigeria. There are currently 10 described species in this genus.
Brachypetersius is a genus of African tetras found in Middle Africa. There are currently six described species.
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).
Iguanodectes is a genus of freshwater fish found in tropical South America, with eight currently described species. They are all small tetras, none longer than 5 inches, and often have attractive silvery or striped scales, which makes them a target for the ornamental fish industry. Alongside the genus Piabucus, it is in the subfamily Iguanodectinae, which in turn is in the family Iguanodectidae. The genus Bryconops, which is also in Iguanodectidae, makes up a sister clade to Iguanodectinae.
Jacques Géry was a French ichthyologist. He was also a scientist and a Doctor of Medicine.
Heiko Bleher is a German researcher, author, photographer and filmmaker best known in the scientific community for his contribution to the exploration of fresh and brackish water habitats worldwide and the discovery of many species of fish and aquatic plants, several of which carry his name, discovery location or are named in honor of Bleher's family.
Enteromius is a genus of small to medium-sized cyprinid fish native to tropical Africa. Most species were placed in the genus Barbus.
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.
Phenacogrammus taeniatus is a species of fish in the African tetra family. It is known only from the Sangha River in Cameroon. This species reaches a length of 4.0 cm (1.6 in).
Phenacogrammus deheyni is a species of fish in the African tetra family. It is found in the middle Congo River, the Ruki drainage, of the Mongala and Aruwimi rivers in the Democratic Republic of the Congo, Africa. This species reaches a length of 10.0 cm (3.9 in).
