Although there has been a local decline in the sub-population in the Kidatu and Mtera dams and no where is it particularly common, the species is widespread with no known immediate threats to the main population, and no indication of declines or fluctuations. It is therefore assessed as Least Concern. It is also categorized as Least Concern for eastern and southern Africa regional assessments.

Threats:
Major Threats
The Rovuma system is heavily fished by artisanal gill net fishermen. Braids and pools in the Rovuma system are also poisoned with traditional plant poisons. Elsewhere, this species is suffering negative impacts from commercial and illegal overfishing, pollution and siltation of the waterways, and habitat degradation from deforestation and agricultural encroachment.
