The blue tilapia is primarily a fresh and brackish water fish that occurs in a wide range of habitats such as streams, rivers, lakes and ponds,[1] but it has a high tolerance for salt water and even hypersaline conditions at up to 4.5% salinity (seawater is about 3.5%).[7] It primarily occurs in waters that range from 12 to 32 °C (54–90 °F),[7] but tolerates between 8 and 40 °C (46–104 °F).[3]
