簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 10 - 12; 臀鰭軟條: 12 - 14; 脊椎骨: 33 - 36. Without lateral line, without infraorbital process; with mostly 7 branched dorsal fin rays and 10 branched anal fin rays. Can be distinguished from other Danio species by the following combination of characters: narrow, indistinct dark vertical bars anteriorly on the sides, followed by a wide, indistinct, tapering horizontal stripe to the end of the caudal peduncle; barbels absent.
沒有側線, 沒有眶下的突起; 大部份具有 7個分枝的背鰭鰭條與 10個分枝的臀鰭棘條。 能在組合特徵之後另外地被區分 Danio 種藉由: 狹窄的, 不明顯的深色縱帶前面地側邊上, 跟隨著一個尾梗的寬﹐不明顯的﹐和尖端細水平斑紋到末端; 觸鬚不存在。
Occurs in high concentrations in large rivers, tributaries and ditches in clean, turbid or even polluted water over bedrock or gravel, sand, mud substrates. Fish collected from late March to the middle of April 1995 appeared to be sexually mature (Ref. 36341).
在岩床或礫石，沙子，泥底部上的乾淨﹐混濁的或甚至污染的水大河，支流與溝渠中出現於高的集中。 魚採集自三月下旬到 1995 年四月的中旬了似乎是性成熟.(參考文獻 36341)
