Adults occur in large rivers on the bottom, even with swift current (Ref. 12693). They never enter small streams (Ref. 37770). Found among boulders, often in the white water of the rapids where it apparently is indifferent to the strong current. Feed primarily on prawns but will take small fishes and aquatic insects (Ref. 6868). Spawn in rivers before the rainy season (Ref. 12693). Migrate in schools. Reported to migrate to follow its prey. Also reported that individuals follow Catlocarpio siamensis during the upstream migration (Ref. 37770). Apparently the main upstream migration begins close to the peak of flood when the current is very strong and the water is turbid (Ref. 37770). Sold fresh in markets. Not a highly esteemed food fish, because its fibrous flesh spoils rapidly and can cause illness (Ref. 12693).
出现于在底部上的大河, 与湍急的水流平的.(参考文献 12693) 从不进入小的溪流。 (参考文献 37770) 发现于大圆石中了, 常见于急流的急流中在哪里它显然地是没有反应强的水流。 主要吃虾但是将吃小鱼与水生昆虫.(参考文献 6868) 在河中产卵在雨季之前.(参考文献 12693) 回游成群。 报告回游到追从它的猎物。 也报告它在它的溯溪回游的时候跟随 暹罗印度鲤［Catlocarpio siamensis］ 。 (参考文献 37770) 显然地主要的溯溪回游开始接近洪水的高峰当水流是非常强的，而且水是浑浊的时候.(参考文献 37770) 生鲜贩卖在市场中了。 不是一个深受喜爱的食用鱼, 因为它的纤维肉很快地腐败而且能引起疾病.(参考文献 12693)
