The dikume (Konia dikume) is a critically endangered species of fish in the Cichlidae family. It is endemic to Lake Barombi Mbo in western Cameroon. 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). This species reaches a length of 11.2 centimetres (4.4 in) SL. The Dikume eats mosquito larvae and has high levels of blood haemoglobin, an adaptation to oxygen-poor deep water.
