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).

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.
出現在急流與在慢的流動水.(參考文獻 37771) 它可能是在湄公河流域中單一最豐富的種與一個生態學的關鍵種確定地是。 在泰國，寮國與柬埔寨的分開很遠的地點像 2-3 公尺寬一樣的小在很多的支流中收集了。 根據絕對的數字，它在每年十二月在 Khone 瀑布之下出現在湄公河的主流的主要的迴游是最豐富的魚種-二月與五月-七月, 在哪裡有一個重要的漁民。 可能單一人最重要的對於許多魚食性魚種覓食或者捕食種存在的在那裡, 而且也可能很重地被被地方海豚， Orcaella brevirostris 捕食 . 線索種之一在 Khone 瀑布區域在湄公河主流上面移動的鯉魚魚的大迴游。 大部分的這些秋天代表不能通行的實際障礙到 migrators, 但是他們能被藉由上升大 " hoo" 中的一或者二或者峽道 (最重要地 Hoo Sahong) 與較小的路避開, 如此繞道不能通行的秋天與比較困難的急流。 利用一個策略， " 發現最少的抵抗的路的不斷改變的領導策略 ", 只可能是成功的非常大量的個體何時正在移動。 如移動魚移動，向上游，領導的魚被區段或者無法向前發現一個方法,一些魚折回並且找尋其他的路徑。 因此 migrators 的領導正在不斷地改變, 直到在得到過去的障礙方面，一些領袖是成功的而且和他們記下大量的從者。
