Bleeker (1850, 1858) indicates Ikan Wadder Bettah as the local name of Betta trifasciata Bleeker, 1849 (now Betta picta, Valenciennes, 1846) in the Ambarawa Javanese dialect.

Taggstrålar i ryggfenan (totalt): 1; Mjukstrålar i ryggfenan (totalt): 8-9; Taggstrålar i analfenan 2-3; Mjukstrålar i analfenan: 23 - 24. This species belonging to the Betta pugnax group is differentiated from the others by having the following characters: elongated last branchiostegal ray extending beyond
posterior margin of the operculum; 25-26 total anal-fin rays; 29-30 lateral scales (Ref. 78499).
Facultative air-breathing (Ref. 126274); This species was collected in hill-streams strongly shaded by forest; mostly found in shallow water close to the shores between roots, plants or leaf litter. Some specimens were also collected from the swift flowing area between boulders. Water data from the type locality: colourless, clear and with a pH of 6.2, an electric conductivity of 20-40 µS/cm and a temperature of 24-26 °C (Ref. 78499).
