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.

簡短描述 型態特徵 | 形態測量圖

Diagnosed by having the following combination of characters: A bright red crescent on distal edge of caudal fin; absence of caudal transverse bars; dorsal transverse bars on distal two-thirds of dorsal fin; iridescent blue opercle scales; body dark brown to black; lateral scales 30-32; body depth 24.2-30.1% SL; dorsal-fin origin above lateral scales 15-17 (mode 16); length of dorsal-fin fin base 12.9-18.9% SL; and height of pectoral-fin origin 14.8-18.9% SL (Ref. 56613).
鑑定藉著具有下列的組合特徵: 在尾鰭的末梢部邊緣上的鮮紅色新月; 缺乏尾部的橫跨橫帶; 在末梢部的背鰭中的三分之二上的背部的橫跨橫帶; 藍色虹彩的鰓蓋鱗片; 身體深褐色的到黑色的; 側面的鱗片 30-32; 體高 24.2-30.1% SL; 在側面的鱗片 15-17(模態 16) 上面的背鰭起點; 背鰭長鰭的基底 12.9-18.9% SL; 而且胸鰭起源 14.8-18.9% SL 的高度.(參考文獻 56613)

生物學特性     字彙 (例如 epibenthic)

Facultative air-breathing (Ref. 126274); Occurs usually in stagnant pools and ditches in clear to brown water (Ref. 56613). Found also in lowland swamps and paddy field. Bubble nest builder species (Ref. 57235). Eggs shrink to the bottom and were then collected by one or both parents and were embedded among the foam bubbles in the nest (Ref. 41595).

在清澈的到褐色的水通常生活在污濁的水池與溝渠。 (參考文獻 56613) 也發現於低地的沼澤與稻田野外採集.。 泡巢建立者種.(參考文獻 57235) 卵對底部收縮然後被由一或者雙親收集而且在巢中被埋入泡沫之中。 (參考文獻 41595)
