简单描述
型态特徵 | 形态测量图
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)
