They mix well with non-territorial cichlids, large catfish, tinfoil barbs, garpike, and other big but peaceful fish.Īlthough their meat is somewhat bland compared with cod, salmon, or sea bass, Tilapia are a good source of protein and have been assimilated into the cuisines of many countries. They can also be somewhat aggressive or boisterous, and so need to be kept with other hardy and robust fish. Most of the species are substrate spawners but some are mouthbrooders. They breed easily and grow fast, but are a danger to any smaller fish. Tilapia are easy to keep in aquariums provided they get enough space. In many places, particularly Florida and Australia, feral populations of Tilapia have had detrimental effects on ecosystems. Because Tilapia are large, fast growing, highly fecund, and tolerate a wide variety of water conditions (even marine conditions), once introduced into a habitat they generally establish themselves very quickly. More often, however, the fish have been introduced deliberately for artisinal or industrial scale aquaculture. Some introductions, as in Florida and Texas, were unplanned, often by aquarium specimens being released by their owners after the fish grew too large. But Tilapia species have been introduced widely into tropical fresh and brackish waters around the world. Tilapia species are native to Africa and the Levant (for example the sea of Galilee, where according to legend Jesus used it to feed the 5000, resulting in the nickname St. Each subdivision is identified by an eight-digit numerical code.Tilapia is a genus of freshwater fish in the cichlidae family. The scheme is based on the Harmonized System nomenclature, further extended with Community subdivisions.
