背棘 (总数) : 0; 背的软条 (总数) : 11 - 12; 臀棘: 0; 臀鳍软条: 15 - 17; 脊椎骨: 35 - 36. Complete lateral line, infraorbital process well developed. Distinguished from all other Danio species by its unique color pattern, having a dark stripe somewhat weakly pigmented anterior to vertical from dorsal-fin origin, getting thicker and darker posteriorly, and ending at the base of caudal fin. The most similar species, D. chrysotaeniatus, lacks the infraorbital process, has three rows of pharyngeal teeth, and has the P stripe extending to the end of the caudal-fin rays. Unlike all other striped Danio species so far examined for this character, D. laoensis has only two instead of three or four rows of pharyngeal teeth (Ref. 37788). With 8-9 1/2 branched dorsal rays and 12-14 1/2 branched anal rays (Ref. 43281).
侧线完整又眶下的突起发展良好的。 与所有的其他 Danio 种区分了用它的被有一个深色的斑纹略微模糊的独特的彩色斑纹位于前垂直的从背鳍起点, 在后部地更厚与更深色, 而且终点在尾鳍基底。 最相似的种 , D. chrysotaeniatus, 缺乏眶下的突起, 有三个列的咽齿, 而且有延伸至尾鳍鳍条的末端的 P 斑纹。 到现在为止不像所有的其他有斑纹的 Danio 种为这特徵调查, D. laoensis 只有二取代三或四个列的咽齿.(参考文献 37788) 8-91/2个分枝的背鳍鳍条与 12-141/2个分枝的臀鳍鳍条.(参考文献 43281)
Inhabits clear, rapidly flowing water (Ref. 12693). Found in rapid-running mountain streams of the middle Mekong (Ref. 12975). Feeds on insects and other invertebrates (Ref. 12693).
栖息于清澈又快速流动的水。 (参考文献 12693) 发现于湄公河中游的湍急山地溪流了。 (参考文献 12975) 吃昆虫与其他的无脊椎动物。 (参考文献 12693)
