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. Web Edition (https://www.trussel2.com/acd/). More on author: Regan.
脊椎骨: 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). Body shape (shape guide): fusiform / normal. 成熟的雄魚有更多的密集顏色, 但是當被驚擾時他們變得類似雌性。 兩者都已經鰓蓋有依據反映的光的角而定的藍色到綠色彩虹色的鱗片。 當生活，臀鰭與尾鰭 (與有時背鰭) 末梢部地被被跟隨著一個藍色虹彩的到綠色的邊緣的一個深藍色邊緣毗鄰; 只有一個黑色的末梢部的邊緣是看得見的在保存狀態下。 在組合特徵之後有別於其他 爪哇搏魚〔Betta picta〕 種群的成員藉由: 臀鰭棘條 23-26(模態 26); 子背部的鱗片 5-6(模態); 側面的鱗片 271/2-30(模態); 尾柄深度 14.8-19.7% SL; 頭長 30.3-34.5% SL; 在背鰭起點 25.3-30.1% SL 的體高; 臀鰭基底 47.9-52.7% SL 的長度; 眼間骨寬度 29.2-36.2% HL.(參考文獻 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).
