Description edit
The black tilapia can grow to the recorded maximum length of 35.5 cm (14 inches).[3] The fish is silvery to steel-grey, with white abdomen. There is a red or orange margin on the dorsal and grey or black marblings on the gill-cover.[4] The species are only reported to be found in fresh water at low altitudes and latitudes which suggests its relatively low salinity and temperature tolerances.[5]
Distribution edit
The species are mainly found in the lower Zambezi river and other rivers southwards such as Runde, Pungwe, Rovuma and Buzi river.[6] It is also found in the lakes nearby.[7]
