Inhabits large free flowing clear rivers, small streams, drainage ditches and artificial ponds and impoundments (Ref. 11225). Feeds on zooplankton, detritus, higher plants and sometimes on the scales of fish. Gametogenesis takes place during the dry season in time for reproduction to begin during the rainy season (Ref. 12225). Reproduction could be carried out in captivity (Ref. 27188).
