背的软条 (总数) : 12 - 16; 臀鳍软条: 15 - 20; 脊椎骨: 34 - 36. Devario malabaricus differs from all its congeners by the combination of the following characters: absence of process on 1st infraorbital; body depth 27-35 %SL; predorsal scales15-17; dorsal fin with 11½-12½ branched rays; anal fin with 12½-17½ branched rays; presence of danionin notch; origin of dorsal fin to hypural distance when carried forward falling well short of posterior border of eye; tip of pectoral fin almost reaching origin of pelvic fin when adpressed; snout length subequal to or greater than eye diameter; P stripe originating level with pelvic-fin origin, 1-2 scale-widths anterior to dorsal-fin origin; P-1 stripe less than half width of P stripe, bifurcated anteriorly by a more or less broken whitish line; 5-6 dark, irregular, vertical bars on the anterior half of body; and absence of nuptial tubercles in both sexes (ref. 118056).
Body shape (shape guide): fusiform / normal.
Found in a variety of habitats from boulder-strewn mountain torrents to small pools in dry zone streams. Most common in flowing water than in reservoirs and tanks. Adults form medium sized shoals and prefer flowing water. They feed on terrestrial insects and detritus. They spawn in shallow water, among marginal weeds and roots usually after heavy rains. Eggs are light orange and sticky; more than 200 eggs are laid and hatch in 1-2 days. Fry are free-swimming on fifth day. They exhibit cannibalism on eggs (Ref. 6028). Individuals rarely reach 12 cm (Ref. 41236). Migratory behaviour is undetermined (Ref. 126106).
发现于从圆石散布的山区急流到干地溪流中的小水潭的多种栖息地了。 常见于流动水超过在水库与水族箱中。 形成中等大小的浅滩而且偏爱流动的水。 吃陆栖的昆虫与碎屑。 产卵在浅水区, 在杂草丛与根之中通常在豪雨之后。 卵是淡的橘色而黏黏的; 超过 200个卵生产而且每天在 1-2 中孵化。 鱼苗在第五个天是游离于水中。 在卵上的展现嗜食同类.(参考文献 6028) 很少达到 12 公分。 (参考文献 41236)
