The species is endemic to the crater Lake Bermin. The species is currently major threat is from oil plantations and slash and burn agriculture leading to sedimentation and pollution in the lake (one location). There is also a potential threat from the lake 'burping' - CO2 (as in Lake Nyos and Lake Barombi-Mbo). In addition deforestation of the surroundings of the crater may cause more wind which could lead to the lake 'turning', as the lake is stratified, lower layer being very low in oxygen and high in organic matter. Higher winds may cause currents in the lake which could cause this lower layer to mix with the upper layer where the fish live. This would cause a massive decrease in oxygen in the water and kills the fish.

|Habitat and Ecology:||This species is benthopelagic.|
|Major Threat(s):||The species is potentially threatened by crater lake 'burping' - CO2 gasses (pers. comm., Brummet, R.) as in Lake Nyos and Lake Baromni-Mbo. Deforestation, palm oil plantation and slash and burn agriculture are leading to pollution and sedimentation of the lake. Deforestation of the area surrounding the lake would lead to increased wind and therefore risk of turnover (it is a stratified lake, where the lower part is very low in oxygen and high in organic matter). This would destroy the top stratified layer where the fish live.|
