简单描述
检索表 | 型态特徵 | 形态测量图
背的软条 (总数) : 11 - 14; 臀鳍软条: 12 - 13; 脊椎骨: 35 - 37. With complete lateral line, well-developed infraorbital process, with mostly 9 branched dorsal-fin rays and 9-10 branched anal-fin rays. Danio acrostomus can be distinguished from all other Danio species by its sharp, upwards directed pointed mouth, relatively long snout (greater than eye diameter), long rostral barbels, and heavily pigmented body. The most similar species D. aequipinnatus auct., has a comparatively blunt and also shorter snout (its length less than the eye diameter) and shorter rostral barbels.
具有侧线完整, 发展良好的眶下突起, 大部份具有 9个分枝的背鳍鳍条与 9-10个分枝的臀鳍棘条。 Danio acrostomus 能被与全部其他的 Danio 种区分用它的锐利, 向上的直接尖嘴，相当长的吻 (大于眼直径) ，长的嘴触须, 而且颜色深的身体。 最相似的种 D. aequipinnatus auct。, 有一个比较钝而比较短的吻 (它的长度少于眼直径) 与比较短的嘴触须。
Found in pools in small forest streams, sometimes even on remnant pools on very steep slopes (about 35°) and also in a mainstream at localities with various gradients, from standing to relatively swift waters. All these habitats have clear to very clear water and forest cover (except downstream of the falls where during the dry season, most of the stream is covered by large basalt blocks or disappears in underground channels in the basalt).
发现于在小的森林溪流中的水池了, 有时甚至在最陡坡 (大约 35个 °) 上的残余水潭上以及在主流方面位于各种不同的坡度, 从站着到相当急流的水域。 这些栖息地有清澈的对最清澈的水域与森林遮盖.(除了瀑布下游以外在哪里在乾季的时候, 大部分的水流被大的玄武岩石块盖着或者在玄武岩中的地下峡道中消失)
