A very tenacious species that can live in foul water and a surface dweller that consumes insects, algae and small fish.  Breeding period varies from April to September. During the study period, the physicochemical parameters were recorded as follows: water temperature 18-28 °C, pH 6.5-7.5, dissolved oxygen 4.5-5.0 mg/l and transparency 45-60 cm for a water body 1.0-1.8 m deep.  In the study area, it represents 15-20% of the total <i>Nandus</i> catch (Ref. 93873).
