形態学 | 形態計測学
背鰭 (合計): 11-14; 臀鰭: 12 - 13; 脊つい: 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.
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).
