Its diet consists of feeds on small invertebrates sifted from the sediment. The maximum total length is 6cm (02inches). It is not considered a threatened species by the IUCN.
The specific name honours the Chief Fisheries Officer for Malawi, J. Stoneman, who helped ensure the success of the expedition the type was collected on.[1]
