Adults differ from all other South Asian Puntius by a combination of the following characters: branched dorsal-fin rays prolonged into filament-like extensions in adult males only; a black band about as wide as the eye near tip of each caudal-fin lobe; lower lip continuous; a caudal blotch on 2-5 scales, commencing posterior to anal-fin origin; no distinct markings on body in advance of anal-fin origin. Distinguished from P. assimilis by possessing a subterminal mouth (vs. Inferior); maxillary barbels shorter, 0.5-2.2 of SL % (vs. 5.5-9.3%); post-orbital head length 11.0-12.1% of SL (vs. 8.7-10.4%); and interorbital width 11.2-12.2% of SL (vs. 10.0-11.1%) (Ref. 55036).
成鱼借着下列特征的一个组合不同于所有其他南亚 Puntius: 分枝的背鳍鳍条只在雄性成鱼中延长到像丝状突起一样的延长内了; 一条黑色的条纹大约等宽于在每个尾鳍叶的顶端附近的眼; 下唇连续; 在 2-5个鳞片上的一个尾部的斑块, 开始在臀鳍起源后面; 没有在身体上的明显的斑纹在臀鳍起源前面。 藉由持有一个接近端位的嘴与 P. assimilis 区分了;(vs. 下方的) 上颌骨触须比较短的, SL 中的 0.5-2.2%;(vs.5.5-9.3%) 后眼窝的头长 11.0-12.1% 的 SL;(vs.8.7-10.4%) 而且眼間骨寬度 11.2-12.2% 的 SL(vs.10.0-11.1%).(參考文獻 55036)
描述: 胸鰭有一單一的與 14 或 15個分支條。 在身體上側線有 18,190 r 20個鱗片, 在到尾鰭基底上延伸 1-3個鱗片。 (參考文獻 55036)
Occurs in clear streams, lakes and ponds (Ref. 41236). Inhabits lowland rivers and also estuaries, reservoirs and marshes (Ref. 55036).
