Tilapia are one of the most frequently cultured fish in the world, with the aquaculture of Tilapia considered a nutritious and healthy part of a balanced diet. Tilapia can be raised in ponds or tanks. While Tilapia can survive in temperatures ranging from 55˚ - 100˚ F, optimal temperatures range from 75˚ - 85˚ F. Breeding Tilapia is relatively easy to do, though sexing them as juveniles is quite difficult; typically, those interested in breeding either order a breeding colony or they order a group of juveniles and allow them to mature together, then move established breeding colonies to their own tank.
