It is the world's longest freshwater lake. The lake is shared among 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.
The aquatic genet, also known as the fishing genet, is a genet that has only been recorded in the northeast of the Democratic Republic of the Congo. Since it is only known from about 30 specimens in zoological collections, it had been listed as Data Deficient on the IUCN Red List since 1996, as it is considered one of Africa's rarest carnivores. In 2015, it has been reassessed as Near Threatened.

Heterochromis is a genus of cichlid fish in the order Perciformes. It is the only genus of the subfamily Heterochromidinae, and contains a single species, Heterochromis multidens, which is endemic to the Congo River Basin in Central Africa. The relationships of Heterochromis to other cichlids have long been controversial, with several morphological features suggesting that it is more closely related to American cichlids than to other African species. Molecular studies have given contradictory results. The most comprehensive analysis done to date found more support for relationship to African cichlids, but could not conclusively reject a relationship to the American clade.

The yellow-tailed African tetra is a freshwater fish that lives in the Congo River basin. It is found in both the Democratic Republic of the Congo and the Republic of the Congo. It is an omnivore in the wild which feeds on crustaceans, fallen fruits and small insects, but seems to have little difficulty in adjusting to normal aquarium foods. though they can be fed in aquarium with daphnia, bloostorm and artemia along good quality dried flakes and granules at least some of which should include additional plant or algal content. The species can tolerate water up to 20 degrees DH, though it does better in softer water. A temperature of 22–26 °C (72–79 °F) and a pH of between 5.0 and 7.5 and a hardness of between 36 and 268ppm is suitable. adult male are more colorful and tend to grow faster than females. males also develops extended white-tipped dorsal, ventral, caudal and anal fins which females lack. it is an egg scattered exhibiting no parental care, and one method of breeding is apparently to keep a group of adults in their own aquarium furnished with a kind of artificial trap, checking it regularly as much as possible especially for eggs. these are removed and normally hatched in smaller containers with the fry being offered microscopic foods until large enough to accept daphnia, bloostorm and the rest.
