Occurs in freshwater coastal swamps and the flood-prone zones of rivers. Gregarious, lives schools which may consist of several hundred fish. Hides under roots, leaves or stocks. Is known to build a nest of bubbles at the surface, defended by the males as the 'Atipas' do. In case of drought, it is reputed to being very resistant and to crawl in search of a new swamp while holding some water in its ears. Feeds on algae and debris (Ref. 35381).
