| Adult biology: | Adults feed predominantly on bottom algae, some of the planktonic organisms that are found in their stomachs are probably those which have settled on the bottom or were washed shorewards from open waters but they do feed directly on plankton (Ref. 2). A maternal mouthbrooder, males make complex courtship structures in the substrate (Ref. 118638). Was a major component of the fisheries catch in Lake Victoria (Ref. 118638). Some pond culture attempted (Ref. 118638). IUCN conservation status is critically endangered (Ref. 118638). | |||
