Abstract

In the River Sombreiro, Nigeria, the dwarf cichlid, Pelvicachromis pulcher was restricted to an upstream zone of cold, soft, acid freshwater. The sites nearest the source had smaller fish. Sex ratio (M:F) was 1:1 except in the most upstream site. Benthic algae, higher plant remains, detritus and copepods were the main food items.
