Comments: Forms schools at the surface.  Prefers to inhabit marshes, small slow-moving creeks or even in main river beds, in the slowest parts of meandering streams next to banks (Ref. 35237).  Voracious carnivore which appears to have a primarily nocturnal habit (Ref. 27188).  During reproduction, the male positions itself beside the female or crosswise in front of her.  Sometimes the male touches the female with his side, pushing her aside in an oblique position, with their heads oriented downwards.  The couple settles next to a bush where the female spawns her eggs (15 to 40).  Eggs adhere to plants by means of sticky filaments which are 2 to 3 mm long.  At 27-30°C, incubation lasts for 9 to 10 days.  Larvae are pelagic and carnivorous (Ref. 35237).  Maximum length 40 cm TL in Keith et al., 2000 (Ref. 35237).
