Conservation: Coptodon thysi est évalué par l\'Union Internationale pour la Conservation de la Nature dans la Liste Rouge des espèces menacées comme étant (CR) en danger critique (2010). Coptodon thysi is currently under major threat from oil plantations and slash-and-burn agriculture leading to sedimentation and pollution in Lake Bermin. 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 of its stratified layers, with the 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 kill the fish (Moelants, 2010).
