The fissi (Sarotherodon caroli) is a species of cichlid endemic to Lake Barombi Mbo in western Cameroon.

This species can reach a length of 18.6 centimetres (7.3 in) SL.

[2] It is threatened 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.
