Congo River The great Congo River (also spelled Kongo River and known as the Zaire River; ; ; ) is the second longest river in Africa, shorter only than the Nile, as well as
Nile tilapia to this species, too. An undescribed population found at, for example, Wami River, Lake Manyara, and Tingaylanda seems to be a close relative. Nile tilapia The Nile tilapia ("Oreochromis niloticus") is a species of tilapia, a cichlid fish native to Africa from Egypt south to east and central Africa, and as far west as Gambia. It is also native to Israel, and numerous introduced populations exist outside its natural range (e.g., Brazil). It is also commercially known as mango fish, "nilotica", or "boulti". The first name leads to easy confusion with another tilapia traded commercially, the mango tilapia ("Sarotherodon galilaeus").
