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.

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).
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).
