成熟度: Lm ?  range ? - ? cm
Max length : 3.8 cm SL 雄鱼/尚未辨别雌雄; (Ref. 137577)
背棘 (总数) : 0; 背的软条 (总数) : 10; 臀棘: 0; 臀鳍软条: 15 - 17. Incomplete lateral line, perforating 9-10 scales; without infraorbital process, with 7 branched dorsal-fin rays and modally 13 branched anal-fin ray. Can be distinguished from all other Danio species by the combination of having two pairs of long barbels, and lacking horizontal dark stripes posteriorly along the sides. The most similar species, D. albolineatus s. str., has a deeper body, possesses two horizontal dark stripes along the posterior part of body, longer rostral barbels (extending beyond instead of not reaching to the posterior margin or orbit), and more vertical scale series along the side (29-30 versus 28) (Ref. 37789). Possesses pink stripe in anal and pelvic fins; white upper and lower margin in caudal (Ref. 43281).
Body shape (shape guide): elongated; Cross section: compressed.
不完全的侧线, 穿孔的 9-10个鳞片; 没有眶下的突起, 7 分枝的背鳍鳍条与典型地 13个分枝的臀鳍鳍条。 能被与全部其他的 Danio 种区分藉由有两对的长触须的组合,而且缺乏水平的深色斑纹在后部地沿着侧边。 最相似的种, D. albolineatus s。 str。, 有一个较深的身体, 持有二条水平的深色斑纹沿着身体后部,更长的嘴的触须 (延伸超过取代不延伸到后面的边缘或者眼窝) 与比较垂直的鳞片系列沿着侧边 (29-30 对 28).(参考文献 37789) 在臀鰭與腹鰭中持有粉紅的斑紋; 白色的上、下邊緣在尾部的.(參考文獻 43281)
Inhabits small streams with relatively cold, running water under forest cover, associated with springs and waterfalls (Ref. 37789). Occurs usually in springs and small creeks, but also found in the Mekong main river (Ref. 43281).
栖息于小的溪流有相当寒冷, 在森林遮盖,被伴随着的泉水与瀑布下面的流动的水.(参考文献 37789) 通常生活在泉水与小溪, 也发现于湄公河主流.(参考文献 43281)
