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.

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..

背的软条 (总数) : 8 - 10; 臀鳍软条: 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).
与 B. waseri 群的另一个成员有下列的组合特徵区分了: pi-在咽喉上的形状的黑色图案; 在臀鳍上的一条明显的中央纵向的斑纹当成鱼时与稚鱼; 而且明显的深蓝色雄性与雌性都有的在臀鳍上的末梢部的边缘.(参考文献 30225)
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).
采集自了沼泽，从一个清除的泥煤沼泽森林的开放区域，具有非常软的且深 (向上到 1.3 公尺 ) 底部。 局限于泥煤 (黄褐色的, 1998)了。 (参考文献 57235)
