The blackchin tilapia is a member of the cichlid and tilapia family. This species is deep-bodied and compressed, with olive to metallic green colouration apparent dorsally, silver with bronze streaks apparent laterally and bright white colouration apparent ventrally. Adults have scattered, irregular black blotches on the lower part of the head, extending onto the body in some individuals. This species has a small mouth, and the black “tilapia spot” is located anteriorly on the base of the second dorsal fin and most prominently on juveniles. The blackchin tilapia inhabits a variety of freshwater, estuarine and marine habitats ranging from creeks and rivers, drainage ditches, canals and ponds to shallow backwater coastal lagoons and bays.
