Adults are distinguished from all other Indian and Sri Lankan Puntius by possessing unique color pattern: a black blotch 2-3 scales wide starting on and above scale 6 or 7 of lateral line series; and another horizontally-elongate, black, tear-shaped blotch about 1 1/2 scales high commencing on lateral line slightly anterior to or above anal-fin origin, on about lateral-line scale row 13 and continuing to caudal fin base (Ref. 55036).
Body shape (shape guide): fusiform / normal.
成鱼被藉由持有独特的彩色斑纹与全部其他的印度洋与斯里兰卡人 Puntius 区分: 一个黑色的斑块 2-3个鳞片广阔地开始与之上上方侧线列的鳞片 6 或 7; 而且另外水平地-延长，黑色 , 泪滴-形状的斑块高度地些微地在侧线上开始的大约 11/2个鳞片位于前或者在臀鳍起源之上, 在大约侧线鳞片列 13 上与连续的到尾鳍基底.(参考文献 55036)
描述: 侧线有 20, 21 或 22个有细孔的鳞片, 加上 2-3个有细孔的鳞片在尾鳍基底上。 胸鳍有一单一的与 14 或 15个分支條.(參考文獻 55036)
Occurs in clear-water, rock and pebble substrate areas (Ref. 55036). Inhabits both slow-flowing pools and relatively fast-flowing areas (Ref. 55036).
