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 - 2; 背的软条 (总数): 7-8; 臀棘 2; 臀鳍软条: 19 - 21. This species is closely related to Betta picta from Java where it can be distinguished in the following characters: fewer dorsal fin rays (mode 8 vs. 9); fewer lateral scales (mode 27 vs. 28); dorsal fin origin above 11-12th lateral scale (vs. 12-14th); anal fin origin below modal 6th lateral scale (vs. 7th); fewer predorsal scales (mode 19 vs. 20); slightly greater anal-fin base length (46.5-50.3% SL vs. 42.6-48.4); anal and caudal fins with reddish distal band in live male (vs. bluish); iridescent greenish-blue opercle scales (vs. yellow-gold); in preserved specimens, male with distinct dorsal transverse bars (vs. faint); male with distinct dark anal distal margin wide (vs. narrow); male without elongated median caudal fin rays (vs. presence); female with distinct caudal transverse bars (vs. very faint or absent); dorsal head view narrow (vs. broad); thick preorbital black stripe (vs. narrow); and the distance between posterior part of anal fin to lower part of caudal narrow (vs. wide) (Ref. 56386).
臀鳍与尾鳍在活的雄鱼中有淡红的色彩末梢部的条纹。 在雄鱼中明显的背部横跨的横带。 母鱼明显的尾部横跨的横带。

生物学特性     字汇 (例如 epibenthic)

Facultative air-breathing (Ref. 126274); Typically found among submerged bank vegetation, in near stagnant waters, with pH 4.7-6.8. Latin word falx means scythe, alluding to the continuous curved shape of the broad anal and caudal distal margins of a male in display. Caudal fin rounded.

典型地发现于水下的河岸植被中了, 在污浊的水域,酸硷值 4.7-6.8 的附近. 拉丁文的字 falx 方法以大镰刀割, 暗示到在显现中的一只雄鱼的宽肛门而尾部末梢部边缘的连续弯曲形状。 尾鳍圆的。
