簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 11 - 14; 臀鰭軟條: 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.
具有側線完整, 發展良好的眶下突起, 大部份具有 9個分枝的背鰭鰭條與 9-10個分枝的臀鰭棘條。 Danio acrostomus 能被與全部其他的 Danio 種區分用它的銳利, 向上的直接尖嘴，相當長的吻 (大於眼直徑) ，長的嘴觸鬚, 而且顏色深的身體。 最相似的種 D. aequipinnatus auct。, 有一個比較鈍而比較短的吻 (它的長度少於眼直徑) 與比較短的嘴觸鬚。
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).
發現於在小的森林溪流中的水池了, 有時甚至在最陡坡 (大約 35個 °) 上的殘餘水潭上以及在主流方面位於各種不同的坡度, 從站著到相當急流的水域。 這些棲息地有清澈的對最清澈的水域與森林遮蓋.(除了瀑布下游以外在哪裡在乾季的時候, 大部分的水流被大的玄武岩石塊蓋著或者在玄武岩中的地下峽道中消失)
