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.

简单描述
型态特徵 | 形态测量图
背棘 (总数): 1; 背的软条 (总数): 8; 臀棘 2; 臀鳍软条: 28. Differs from Betta chloropharynx in the following characters: horseshoe-shaped black throat mark (vs. µ-shaped black throat mark); presence of both dorsal and caudal transverse bars (vs. absence); more subdorsal scales (mode 6 1/2 vs. 5-6). It is distinguished from Betta renata in the following characters: horseshoe-shaped black throat mark (vs. kidney-shaped); non-spotted opercle (vs. spotted opercle); opercle with yellow or brown lower margin (vs. black margin); fewer postdorsal scales (mode 12 vs. 9 1/2); more anal fin rays (mode 30 vs. 29); more lateral scales (mode 32 vs. 31). Can be differentiated from Betta spilotogena in the following characters: horseshoe-shaped black throat mark ((vs. black median spot); non-spotted opercle (vs. spotted opercle); opercle with yellow or brown lower margin (vs. back margin); presence of both dorsal and caudal transverse bars (vs. absence); and more subdorsal scales (mode 6 1/2 vs. 5 1/2) (Ref. 56386).
Facultative air-breathing (Ref. 126274); Occurs in backwater peat swamps with substrate usually peat and leaf litter. Large fish are found in the flowing sections of the blackwater streams and smaller ones appear to prefer pools and slower flowing waters.
用底部通常出现于回流水泥煤沼泽泥煤与腐叶。 大的鱼被发现于死水溪流的流动部分，而且较小的一些似乎偏爱水池与比较慢的流动水域。
