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.

Biologie     Fachlexikon (Englisch) (z.B. 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).
