Bridouxia rotundata was previously assessed as Endangered. The availability of better distributional data has resulted in the species being reassessed as Least Concern.

Bridouxia rotundata is endemic to Lake Tanganyika. Extent of occurrence is estimated at 5,000 km², but the species is known from 56 sites on all four coastlines and it is possible that further surveys may locate more sites for this species. Habitat quality id declining (human settlements and disturbance - no threat from pollution and minimal sedimentation).

Currently assessed as Least Concern, but if some of the sites are historial records only and the species cannot be relocated at these sites, a future reassessment may prove ths species to be at least Near Threatened.
