Etymology: Betta: Malay/Javanese origin. 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. Ikan Wader is a common Javanese name for smaller freshwater fishes, especially cyprinids (already used in Old Javanese). See Blust, R. & Trussel, S. Austronesian Comparative Dictionary.

Động vật có xương sống: 27 - 29. Mature males have more intense coloration, but when disturbed they become similar to the females. Both have opercle with blue to green iridescent scales depending on angle of reflected light. Anal and caudal fins (and sometimes the dorsal fin) are bordered distally by a dark blue edge, followed by an iridescent blue to green border when live; only a blackish distal border is visible when preserved. Differs from other members of the Betta picta species group by the following combination of characters: anal-fin rays 23-26 (mode 26); subdorsal scales 5-6 (mode); lateral scales 27 1/2-30 (mode); caudal peduncle depth 14.8-19.7% SL; head length 30.3-34.5% SL; body depth at dorsal-fin origin 25.3-30.1% SL; length of anal-fin base 47.9-52.7% SL; interorbital width 29.2-36.2% HL (Ref. 56613).
Facultative air-breathing (Ref. 126274); Occurs mostly in fast flowing clear water hill stream (Ref. 56613). Found in the more stagnant stretches of the stream, among the submerged leaf litter, tree root and overhanging bank vegetation (Ref. 56613). A mouth brooder (Ref. 56613).
