Occurs from sea level to at least 2000 m above sea level and is commonly found below waterfalls in isolated mountain streams and on small islands inhabited by few other freshwater fishes (Ref. 2091).

Found in middle to bottom depths in fairly shallow waters where it feeds on zooplankton, insect larvae and some vascular plants. Probably does not migrate (Ref. 12693). |
