Sarotherodon linnellii, sometimes known as the unga,[2] blackfin tilapia or blackbelly tilapia, is a cichlid endemic to Lake Barombi Mbo in western Cameroon. This species reaches a length of 18.5 centimetres (7.3 in) SL.[3] It is critically endangered because of pollution and sedimentation due to human activities. It is potentially also threatened by large emissions of carbon dioxide (CO2) from the lake's bottom (compare Lake Nyos),[1] although studies indicate that Barombo Mbo lacks excess amounts of this gas.[4]

Juveniles mainly feed on insects (including their larvae) and adults mainly on phytoplankton.[3]
