Tilapia (/tÉ¨ËlÉËpiÉ/ ti-LAH-pee-É) is the common name for nearly a hundred species of cichlid fish from the tilapiine cichlid tribe.Tilapia are mainly freshwater fish inhabiting shallow streams, ponds, rivers and lakes and less commonly found living in brackish water.ilapia are unable to survive in temperate climates because they require warm water. The pure strain of the blue tilapia, Oreochromis aureus, has the greatest cold tolerance and dies at 45 Â°F (7 Â°C), while all other species of tilapia will die at a range of 52 to 62 Â°F (11 to 17 Â°C).
Other than their temperature sensitivity, tilapia exist in or can adapt to a very wide range of conditions. One extreme example is the Salton Sea, where tilapia introduced when the water was brackish now live in saltwater so salty that it kills marine fish.arger tilapia species are generally poor community aquarium fish because they eat plants, dig up the bottom, and fight with other fish. However, the larger species are often raised in aquariums as a food source, because they grow rapidly and tolerate high stocking densities and poor water quality.
