The leka keppe or keppi (Sarotherodon lohbergeri) is a species of cichlid essentially endemic to Lake Barombi Mbo in western Cameroon, but additionally two juveniles have been found in the Kumba Stream (Kake River), a tributary of the lake's outlet. This species reaches a length of 16.2 centimetres (6.4 in) SL. It is threatened because of pollution and sedimentation due to human activities, and potentially also by large emissions of carbon dioxide (CO2) from the lake's bottom (compare Lake Nyos).
