The Nile tilapia (Oreochromis niloticus) is a species of tilapia, a cichlid fish native to parts of Africa and the Levant, particularly Israel and Lebanon. Numerous introduced populations exist outside its natural range. It is also commercially known as mango fish (not to be confused with mango tilapia, or Sarotherodon galilaeus), nilotica, or boulti. The Nile tilapia reaches up to in length, and can exceed . As typical of tilapia, males reach a larger size and grow faster than females. Wild, natural-type Nile tilapias are brownish or grayish overall, often with indistinct banding on their body, and the tail is vertically striped. When breeding, males become reddish, especially on their fins. It is commonly confused with the blue tilapita (O. aureus); that species lacks the striped tail pattern, has a red edge to the dorsal fin (this edge is gray or black in Nile tilapia), and males are bluish overall when breeding. The two species can also be separated by meristics. Because many tilapia in aquaculture and introduced around the world are selectively bred variants and/or hybrids, identifying them using the standard features that can be used in the wild, natural types is often not possible. The virtually unknown O. ismailiaensis has a plain tail, but otherwise closely resembles (and may only be a variant of) the Nile tilapia. Regardless, O. ismailiaensis might be extinct, as its only known habitat in northeastern Egypt has disappeared, although similar-looking individuals (perhaps the same) are known from the vicinity. Nile tilapia can live for more than 10 years. The Nile tilapia is native to larger parts of Africa, except Maghreb and almost all of Southern Africa. It is native to tropical West Africa, the Lake Chad basin, and much of the Nile system, including lakes Tana, Albert and Edward–George, as well as lakes Kivu, Tanganyika, and Turkana, and the Awash and Omo Rivers. In Israel, it is native to coastal river basins. It has been widely introduced elsewhere, both in Africa and other continents, including tens of countries in Asia, Europe, North America, and South America.

Oreochromis

Oreochromis is a large genus of oreochromine cichlids, fishes endemic to Africa and the Middle East. A few species from this genus have been introduced far outside their native range and are important in aquaculture. Many others have very small ranges; some are seriously threatened, and O. ismailiaensis and O. lidole possibly are extinct. Although Oreochromis primarily are freshwater fish of rivers, lakes and similar habitats, several species can also thrive in brackish waters and some even survive in hypersaline conditions with a salinity that far surpasses that of seawater.

Lake Edward

Lake Edward (locally Rwitanzigye or Rweru) is one of the smaller African Great Lakes. It is located in the Albertine Rift, the western branch of the East African Rift, on the border between the Democratic Republic of the Congo (DRC) and Uganda, with its northern shore a few kilometres south of the equator. Henry Morton Stanley first saw the lake in 1888, during the Emin Pasha Relief Expedition. The lake was named in honour of Albert Edward, Prince of Wales, son of then British monarch Queen Victoria, and later to become King Edward VII.

Haplochromis

Haplochromis is a ray-finned fish genus in the family Cichlidae. It has been used as the default "wastebin taxon" for Pseudocrenilabrinae cichlids of the East African Rift, and as such became the "largest" fish "genus". Many of these cichlids are popular aquarium fishes; like similar Haplochromini they are known as "haplos", "happies" or "haps" among aquarium enthusiasts. The genus was established by F.M. Hilgendorf in 1888. It was originally conceived as a subgenus of A.C.L.G.
