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.

Facultative air-breathing (Ref. 126274); Inhabit more slow flowing areas of the headwater habitats (Ref. 34011). Found usually in ravines and isolated elevated pools. An adult and several juveniles are usually encountered in submerged leaf litter. Adults may take cover under floating leaves and are excellent jumpers, which may explain their presence in isolated elevated pools (Ref. 56613). Feed mainly on terrestrial insects and occasionally on aquatic invertebrates (Ref. 56613).
棲息於源頭棲息地的更慢流動區域。 (參考文獻 34011) 發現通常在峽谷與孤立的升高水池。 一個成魚與一些稚魚通常在水下的腐葉被見到。 成魚可能採在漂浮的樹葉下面的表面而且是優良的跳躍者, 那可能在孤立的升高水池中解釋他們的出現.(參考文獻 56613) 主要捕食陸棲的昆蟲與偶然地在水生無脊椎動物上.(參考文獻 56613)
