This species is distinguished by the following characters: lateral line incomplete; pored scales rarely more than 24 (mode 8); barbels are well-developed, length reaching but not surpassing 1.8 mm (Ref. 124213).
Cross section: compressed.
It is tolerant of turbid and eutrophic habitats from foothill streams to mainstem sections of major rivers and manmade impoundments and it does not penetrate into upper reaches of mountain tributary streams with oligotrophic water (Ref. 124213). It probably feeds on insects, zooplankton, seeds, green algae and diatoms. Oviparous (Ref. 205). Breeds during summer when rivers are swollen after rain and lays adhesive eggs amongst vegetation. It is probable that it is preyed upon by larger fishes and birds like other species (see Ref. 7248 & 5214).
喜欢较冷的水域。 形成小群鱼群与浅滩, 在来自小的溪流到大河与湖的各种不同的栖息地。 时常伴随着覆盖物与遮蔽物例如掉落的圆木,柴枝或杂草丛。 吃昆虫,浮游动物,种子,绿藻与硅藻。 卵生的.(参考文献 205) 在夏天期间进行繁殖当雨后河水涨高时而且生下在植物中的聚集在一起的卵。 被较大的鱼与鸟 (参考文献 7248&5214) 捕食。
