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/); pulchra: The Latin pulcher means handsome, alluding to the beauty of this fish.

簡短描述

背棘 (總數) : 1 - 2; 背的軟條 (總數) : 8 - 9; 臀棘: 1 - 2; 臀鰭軟條: 22 - 26; 脊椎骨: 29. In comparison with other members of the B. pugnax species group, this can be differentiated by the following combination of characters: presence of chin-bar; absence of dark marks below postorbital stripe on opercle; presence of dorsal transverse bars; caudal transverse bars present only in male; greenish iridescent scales on opercle and body; anal fin with red subdistal border and black edge; caudal fin without distal dark edge; anal-fin rays 24-28 (mode 26); lateral scales 28-30 (mode 29); postdorsal scales 10-11 (mode 10); pelvic fin length 29.1-53.2% SL; head length 32.7-37.6% SL; inter-orbital width 34.3-41.8% HL (Ref. 56613).
在比較中 B. pugnax 種群的與其它的成員在一起, 這能被藉由下列的組合特徵區別: 有下巴-橫帶; 在鰓蓋上在眼眶後的斑紋之下缺乏深色印記; 有背部的橫跨橫帶; 尾部的橫跨橫帶只出現在雄魚; 在鰓蓋與身體上的呈綠色的彩虹色的鱗片; 臀鰭有紅色的子末梢部的邊緣與黑邊; 沒有末梢部的深色邊緣的尾鰭; 臀鰭棘條 24-28(模態 26); 側面的鱗片 28-30(模態 29); 後背的鱗片 10-11(模態 10); 腹鰭長度 29.1-53.2% SL; 頭長 32.7-37.6% SL; 在眼窩之間的寬度 34.3-41.8% HL.(參考文獻 56613)
Facultative air-breathing (Ref. 126274); Inhabits peat swamp forests (Ref. 84801). Occurs in blackwater habitats and commonly found only in the overgrown bank vegetation of the irrigation canals. Paternal Mouth brooder (Ref. 13220).
出現於死水的棲息地與通常發現只在灌溉管的發育過度河岸植被中。 父親的口孵魚.(參考文獻 13220)
