Facultative air-breathing (Ref. 126274); The type locality was described as a small river with current (0.4 m/s); ground formed by gravel and in parts by sand. The fighting fishes were found at the banks, slower current , between roots and plants (Araceae). Water data as described: pH 5.8-6.3, 30-52 µS/cm, 23.3- 24.2 °C. Type specimens in February 2005 with pH 6.3, electric conductivity 51 µS/cm and water-temperature 25.5 °C (Ref. 78499).
