This species is distinguished from its congeners by the following set of characters: mouth subterminal, weakly oblique to nearly horizontal (less than or equal to 20° to midline of body); maxillary barbels are almost always present (rarely absent); edge of rostral cap with a distinct medial indent; flank immaculate, no longitudinal stripes; caudal peduncle immaculate or with brown to black spot at the medial insertion of caudal fin; caudal fin mostly clear, with scattered melanophores; pectoral, pelvic, and anal fins hyaline in life (Ref. 123185).
一种小的种, 正好在 10 公分 SL 之上的大被记录的标本; 吻但是不常强烈突出; 头部相当小的, 尤其相较于那接近地讲与略微大型鱼种 C. siamensis; 如此远有别于所有的其他种的 Cirrhinus 当知道在有一个雌性先熟的雌雄同体.(参考文献 33488) 身体银色的计划.(参考文献 43281)
Occur in rapids and in slow flowing water (Ref. 37771). It may be the single most abundant species in the Mekong basin and is certainly an ecological keystone species. Collected in numerous tributaries as small as 2-3 m wide in widely separated localities in Thailand, Laos and Cambodia. In terms of absolute numbers, it is the most abundant fish species in the major migrations that occur in the mainstream of the Mekong River below Khone Falls every December-February and May-July, where there is an important artisanal fisheries. Probably the single most important forage or prey species for many piscivore fish species present there, and may also be heavily preyed upon by the local dolphin, Orcaella brevirostris . Is one of the lead species in the massive migrations of cyprinid fishes moving up the Mekong mainstream in the Khone Falls area. Most of these falls represent an impassable physical obstacle to the migrators, but they can be avoided by going up one or two of the large "hoo" or channels (most importantly Hoo Sahong) and smaller pathways, thus by-passing the impassable falls and more difficult rapids. Employs a strategy, "the ever-changing leadership strategy for finding the pathway of least resistance", which can only be successful when very large numbers of individuals are migrating. As the migrating fish move upstream, the leading fish are blocked or fail to find a way onwards, some fish turn back and look for other routes. Therefore the leadership of the migrators is constantly changing, until some leaders are successful in getting past obstacles and take large numbers of followers with them.
出现在急流与在慢的流动水.(参考文献 37771) 它可能是在湄公河流域中单一最丰富的种与一个生态学的关键种确定地是。 在泰国，老挝与柬埔寨的分开很远的地点像 2-3 公尺宽一样的小在很多的支流中收集了。 根据绝对的数字，它在每年十二月在 Khone 瀑布之下出现在湄公河的主流的主要的回游是最丰富的鱼种-二月与五月-七月, 在哪里有一个重要的渔民。 可能单一人最重要的对于许多鱼食性鱼种觅食或者捕食种存在的在哪里, 而且也可能很重地被被地方海豚， Orcaella brevirostris 捕食 . 线索种之一在 Khone 瀑布区域在湄公河主流上面移动的鲤鱼鱼的大回游。 大部分的这些秋天代表不能通行的实际障碍到 migrators, 但是他们能被藉由上升大 " hoo" 中的一或者二或者峡道 (最重要地 Hoo Sahong) 与较小的路避开, 如此绕道不能通行的秋天与比较困难的急流。 利用一个策略， " 发现最少的抵抗的路的不断改变的领导策略 ", 只可能是成功的非常大量的个体何时正在移动。 如移动鱼移动，向上游，领导的鱼被区段或者无法向前发现一个方法,一些鱼折回并且找寻其他的路径。 因此 migrators 的领导正在不断地改变, 直到在得到过去的障碍方面，一些领袖是成功的而且和他们记下大量的从者。
