Justification:
The estimated extent of occurrence is over 50,000 km² but the area of occupancy is less than 2,000 km². It is only known from three locations. The main threats posed to this fish species include effluents from mining activities in the Pra, and urbanisation and agricultural development in Ghana. These effluents may contain heavy metals like arsenic, mercury and compounds like cyanide. Also, the removal of vegetation pertaining to mining activities, and commercial timber felling, may cause increasing sediment loads, and its attendant problems to the life of the fish. Another major threat is pollution of the water bodies by inadequately treated human waste and by domestic discharges arising from increasing residential developments. The species is therefore assessed as Vulnerable.
