简单描述
检索表 | 型态特徵 | 形态测量图
背的软条 (总数) : 12 - 13; 臀鳍软条: 15 - 16; 脊椎骨: 33 - 35. With lateral line complete, comprising 31-36; infraorbital process present; branched dorsal fin rays 9-10, branched anal fin rays 11-13. Distinguished from all other Danio species by its color pattern, which includes three dark horizontal stripes separated by three light horizontal interspaces on the side of the body. All three stripes taper posteriad. Stripes and interspaces are narrow, about equal in width. The primary stripe runs along the mid-line of the side and extends to the end of median caudal fin interradial membranes. The P + 1 and P - 1 stripes are separated from the P stripe by a light interspace about half scale wide. Above the P + 1 stripe I + 2 interspace separating it from the dark back of the body. This species can be separated from the most similar species, D. aequipinnatus auct., by having almost equally wide, complete three stripes and three interspaces. By contrast D. aequipinnatus auct. has the P stripe wider and darker than other dark stripes and (1) invaded anteriorly by small light spots derived from the light stripe (I - 1) running immediately ventral to the P stripe or (2) interrupted anteriorly on the side by numerous vertical narrow light bars derived from the light stripes (I + 1 and I - 1) running immediately above and below the P stripe.
具有侧线完整, 包含 31-36; 眶下的突起呈现; 分枝的背鳍鳍条 9-10, 分枝的臀鳍棘条 11-13. 用它的彩色斑纹与所有的其他 Danio 种区分了, 包括被分开三个淡的水平间隙的三条深色的水平斑纹在身体侧边上。 所有的三条斑纹成锥形 posteriad 。 斑纹与间隙是狭窄的, 大约宽度相等。 初期的斑纹沿着侧边的中线而且延伸到中央尾鳍间辐膜的末端。 P+1 与 P- 1条斑纹广阔地被淡间隙与 P 斑纹分开大约一半鳞片。 在 P+1 斑纹 I+2 之上留分开它从身體的深色背面的間隔。 這種能被與最相似的種， D. aequipinnatus auct 分開。, 藉著具有幾乎寬度一樣, 完全的三條斑紋與三個間隙。 藉著差別 D. aequipinnatus auct。 讓 P 斑紋比較寬而且顏色更深其他的深色斑紋而且 (1) 前面地被小淡色的斑點侵入衍生的從淡色條紋 (I- 1) 跑緊鄰腹的到 P 斑紋或 (2) 前面地側邊上被很多垂直的狹窄淺色的橫帶中斷衍生了從淡色條紋 (I+1 與 I- 1) 跑緊鄰上面與下面 P 斑紋。
