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.

Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 1 - 3; Raggi dorsali molli (totale) : 8 - 13; Spine anali: 1 - 3; Raggi anali molli: 23 - 31.
Facultative air-breathing (Ref. 126274); Found in a peat swamp forest (Ref. 84801), mostly in well shaded shallow waters (less than a meter deep) or along the vegetated banks of deeper streams. Occurs usually in slow flowing water. Preferred substrate appears to be leaf litter or submerged detritus. Builds a bubble nest, with the male aggressively chasing the female to below the nest (Ref. 13213) .
