Ecology of Nannocharax usongo
 
Main Ref. Dunz, A.R. and U.K. Schliewen, 2009
Remarks Type specimens of Nannocharax usongo were collected on logs in areas of relatively rapid water movement while snorkeling; these had a very rugged surface due to being partially decomposed by wood eating Povilla (Ephemeroptera) larvae; individuals were spaced singly and moved very rapidly around the log surface, but always with close contact to it and never reaching out into the free water column (Ref. 80507).
