Petrochromis is a genus of cichlids endemic to Lake Tanganyika in east Africa. [1]
There are currently 8 recognized species are in this genus: [1]
Lake Tanganyika is an African Great Lake. It is the second-oldest freshwater lake in the world, the second-largest by volume, and the second-deepest, in all cases after Lake Baikal in Siberia. It is the world's longest freshwater lake. The lake is shared between four countries – Tanzania, the Democratic Republic of the Congo (DRC), Burundi, and Zambia, with Tanzania (46%) and DRC (40%) possessing the majority of the lake. It drains into the Congo River system and ultimately into the Atlantic Ocean.
Julidochromis is a genus of cichlids in the subfamily Pseudocrenilabrinae. They are commonly called julies and are endemic to Lake Tanganyika in eastern Africa. This genus includes six formally described species, some with a number local variants of uncertain taxonomic status. Further taxonomic work is required to determine how many species exist; the closely related Chalinochromis with two more species is sometimes included here and this may be correct. Hybridization makes attempts to determine relationships with molecular phylogenetic methods difficult.
Variabilichromis moorii has no common name and is a species of freshwater cichlid endemic to Lake Tanganyika in eastern Africa. It is a small ovate bodied fish named for an early collector of fish from the lake, John Edmund Sharrock Moore (1870-1947) who was a cytologist, zoologist and led an expedition to Lake Tanganyika and who discovered this species. Juveniles are usually yellow, and adults are dark brown to black in color. It reaches a total length (TL) of 10.3 centimetres (4.1 in). Currently it is the only member of its genus. V. moorii feeds on algae, zooplankton, and benthic invertebrates. It is also found in the aquarium trade.
Cyphotilapia is a small genus of African cichlids endemic to Lake Tanganyika, with C. frontosa being roughly confined to the northern half of the lake and C. gibberosa roughly to the southern half. They have a distinctly banded pattern, bulbous foreheads when mature and can reach up to 33 cm in length.
Cyprichromis is a genus of cichlids with five species. They are also known as the herring cichlids or sardine cichlids, since they form large schools in the open water of Lake Tanganyika. Of the known species, only C. microlepidotus has been recorded outside Lake Tanganyika.
Gnathochromis is a small genus of cichlid fish endemic to the Lake Tanganyika basin in East Africa.
Lepidiolamprologus is a small genus of cichlids endemic to Lake Tanganyika in eastern Africa. It is closely related to Altolamprologus. and there is the possibility that a revision of the genus could see more species added.
Ophthalmotilapia is a small genus of four cichlid species endemic to Lake Tanganyika in East Africa.
Xenotilapia is a genus of cichlids species endemic to Lake Tanganyika in east Africa.
Bathybates is a genus of piscivorous cichlids endemic to Lake Tanganyika in East Africa. The genus includes both pelagic species that mainly feed on Tanganyika sardines and benthic species that mainly feed on other cichlids. They are some of the deepest-living cichlids, regularly occurring down to 200 m (660 ft).
Synodontis is the largest genus of mochokid catfishes. It is the biggest genus within the 10 genera and 190 different species in the family Mochokidae. Synodontis has over 131 different species within the genus. Synodontis are also known as squeakers, due to their ability to make stridulatory sounds through their pectoral fin spines when handled or disturbed. Synodontis make a sound that sounds like squeaking by rubbing their spines together. They do this when they have been frightened or when they become angry. Synodontis may also squeak when they are taken out of the water. These catfish are small- to medium-sized fish with many species exhibiting attractive spotted markings. Some species are also known for naturally swimming belly-up, earning the name upside-down catfish. Some of these species are Synodontis contractus and Synodontis nigriventris. While some of these species are known to swim upside down, another species, Synodontis multipunctatus, is a brood parasitic cuckoo catfish.
Lepidophagy is a specialised feeding behaviour in fish that involves eating of scales of other fish. Lepidophagy is widespread, having been independently evolved in at least five freshwater families and seven marine families. A related feeding behavior is pterygophagy, which are fish that feed on the fins of other fish.
The giant cichlid, also known as the emperor cichlid, is a species of fish in the family Cichlidae, endemic to Lake Tanganyika in Africa. It is the only member of its genus Boulengerochromis and tribe Boulengerochromini.
Trematochromis benthicola is a ray-finned fish species in the cichlid family (Cichlidae), subfamily Pseudocrenilabrinae and the tribe Haplochromini. It is found throughout Lake Tanganyika in the Burundian, the Democratic Republic of the Congo, Tanzanian, and Zambian shoreline. Its preferred habitat are the hidden recesses of caves in shallow water.
Gnathochromis pfefferi is an African species of fish in the family Cichlidae. It is endemic to Lake Tanganyika and its slow-flowing tributaries in the countries of Burundi, the Democratic Republic of the Congo, Tanzania and Zambia. It is common and widespread. This cichlid is found in relatively shallow waters, typically over soft bottoms in places with aquatic grasses.
Haplotaxodon is a genus of cichlids endemic to Lake Tanganyika in Africa.
Perissodus is a genus of cichlids endemic to Lake Tanganyika in Africa. They feed on scales.
Plecodus elaviae is a species of cichlid endemic to Lake Tanganyika. This schooling species is a scale-eater, plucking scales from other fishes. Both parents care for the offspring in this mouthbrooder. This fish can reach a length of 32 centimetres (13 in) TL.
Plecodus is a genus of cichlids endemic to Lake Tanganyika in Africa. They feed on scales.
Cichlidogyrus is a genus of monopisthocotylean monogeneans in the family Ancyrocephalidae. The type-species of the genus is Cichlidogyrus arthracanthusPaperna, 1960, by original designation. All the species of the genus are parasites on the gills of fish, namely African Cichlidae, Nandidae and Cyprinodontidae.
