This species has only been observed in Lake Tanganyika in the three sub-basins on the Tanzanian and Zambian sides. Despite its small size, this species is never abundant in the alkaline, moderately mineral-rich and highly transparent lake. It is typically found on sandy substrates (sometimes with mollusk shells) or submerged rocks between 9 and
