简单描述 型态特徵 | 形态测量图

背的软条 (总数): 14-15; 臀鳍软条: 16 - 18. Devario pathirana differs from all its congeners by the combination of the following characters: body consisting of 8-9 dark, irregular bars between pectoral-fin origin and caudal-peduncle origin; absence of P+1 and P-1 stripes; body depth 30-33 %SL; snout length less than eye diameter; 14-15 predorsal scales; dorsal fin with 11½-12½ branched rays; anal fin with 14½ branched rays; a blunt, knob-like process on 1st infraorbital; presence of danionin notch; origin of dorsal fin to hypural distance when carried forward reaching middle of eye; pectoral fin, when adpressed, just reaching origin of pelvic fin (Ref. 118056).
包含一些 7-11 的显著彩色斑纹不规则的﹐平行的, 深蓝色纵带在侧边与一条短的纵向斑纹上的较前端在尾梗上, 在中央的尾部鳍条中继续.(参考文献 6874) 描述: 背鳍有 3 单一的与 11-12个分支条; 臀鳍有 3 单一的与 13-15个分支条; 胸鳍有一单一的与 11-13 分支条; 而且腹鳍有一单一的与 7个分支条.(参考文献 6874)

生物学特性     字汇 (例如 epibenthic)

Occurs in still pools to swift flowing streams with pebble or boulder substrates, seldom over sand. Has not been found in silted rivulets flowing into mainstream. More sedentary than D. malabaricus. Forms groups of 3-5 individuals slowly moving near the surface. Probably feeds on insects. Aquarium fish exporters voluntarily refrained from collecting this species until it was better understood and bred commercially. Collected in moderate numbers.

迅速地出现于静止的水池到用小圆石或大圆石底部流动溪流, 很少在沙子之上。 没有被发现于流入主流的被淤泥的小河。 比 D. malabaricus 更定栖. 形成 3-5个个体的鱼群慢慢地移动接近水表面。 可能吃昆虫。 水族馆鱼输出者自动地克制不要收集这种了,直到它被了解得更好而且经济性的饲养。 在一般的数量中收集了。
