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. Web Edition (https://www.trussel2.com/acd/); pi: Specific epithet from the Greek letter (pi), as an allusion to the shape of its throat marking.

背的軟條 (總數) : 8 - 10; 臀鰭軟條: 30 - 32; 脊椎骨: 31 - 33. Differs from other members of the B. waseri group by having the unique suite of characters: a pi-shaped black pattern on the throat; opercle usually with scales, without green scales; lower margin of opercle black, black spots on opercle; absence of dorsal and caudal-fin transverse bars; broad and distinct dark blue anal margin; predorsal scales 24-25; subdorsal scales 5 1/2-6 (mode 6); postdorsal scales 10-12 (mode 11); lateral scales 32-33 (mode 33); dorsal-fin rays 8-10 (mode 9); anal-fin rays 30-32 (mode 31); head length 32.3-34.4 % SL; body depth 26.4-29.7% SL (Ref. 56613).
Body shape (shape guide): fusiform / normal.
有別於其他 B. waseri 群的成員藉著具有特徵的獨特隨員: pi-在咽喉上的形狀的黑色圖案; 鰓蓋通常有鱗片, 沒有綠色的鱗片; 鰓蓋在鰓蓋上的黑色又黑色的斑點下緣; 缺乏背鰭與尾鰭-鰭橫跨的橫帶; 寬與明顯的深藍色肛門的邊緣; 前背的鱗片 24-25; 子背部的鱗片 5 1/2-6(模態 6); 後背的鱗片 10-12(模態 11); 側面的鱗片 32-33(模態 33); 背鰭鰭條 8-10(模態 9); 臀鰭棘條 30-32(模態 31); 頭長 32.3-34.4% SL; 體高 26.4-29.7% SL.(參考文獻 56613)
Facultative air-breathing (Ref. 126274); Primarily found in well shaded peat forest blackwater swamps and creeks which drained out such swamps; the beds are usually covered with dense leaf litter and lots of roots and plants. The free water area is often small, with pH of about 6.0 (Ref. 78499); very soft and deep (up to 1.3 m ) substrate (Ref. 57235).
採集自了從一個清除的泥煤沼澤森林的開放區域的沼澤具有非常軟的且深 (向上到 1.3 公尺 ) 底部。
