Inhabits slow and shallow waters of rivers of plains and estuaries; never available above an altitude of 366 m. Also found in canals, streams, beels, ponds and inundated fields (Ref. 1479). Has been placed into aquaria and kept by hobbyists; it stays on the bottom and spawns in the upper water-level. The more slender and generally smaller males pursue the female in courtship; several males may join in.
