This species is distinguished from its congeners by the following set of characters: mouth terminal, strongly oblique (35–45° to midline of body); no maxillary barbels; edge of rostral cap is straight, no medial indent; flank immaculate, no longitudinal stripes; caudal peduncle immaculate, no spot; caudal fin mostly clear, with scattered melanophores; in life, pectoral, pelvic, and anal fins hyaline (Ref. 123185).
头部大而宽的, 宽度 5.5-6.7 标准体长比率; 相当深的身体,3.2-3.4 标准体长比率; 吻不或微弱突出的; 单色的银色身体.(参考文献 43281)
Often found in great abundance at midwater to bottoms depths in large and small rivers. Feeds on algae, periphyton and phytoplankton. Not known to prosper in impoundments. Well known for its annual trophic migrations out to the floodplains in wet season. Returns to rivers as water levels begin to fall in October with numbers increasing through December and then slowly declining (Ref. 12693). From just upstream Phnom Penh in Cambodia to the Khone Falls this species is reported to migrate upstream during the period October-February. At Muk Kompul in Kandal Province, it migrates upstream just before the full moon. Further upstream near Kratie, migration occurs during full moon and at Sambor, migration takes place immediately after full moon. Near the Khone Falls, upstream movements continue through March but in April fish are moving in both direction. From May to July, at the start of the rainy season, it migrates downstream from the Khone Falls to the Mekong Delta. Here, the fish is reported to move out of the Mekong into canals and flooded areas in August-September. When water recedes in November-December, fish migrates to the Mekong again. Upstream the Khone Falls near Ubolratchatani in Thailand, this species moves upstream between February and June, consisting mainly of juveniles in February-March and of adults (15-20 cm) in April-June. Further upstream from Xayabouri in Laos to Chiang Khong in Thailand, upstream migrations takes place between March to July, first by juveniles, later by adults (Ref. 37770). Used to make prahoc along the Tonlé Sap, Cambodia. Often seen in the aquarium trade (Ref. 12693).
较大时在中层水域到深底部时常大量发现与小的河。 吃藻类，固着生物与浮游植物。 不知道在圈围水域兴隆。 广为人知的出自在湿季中的到洪泛区的它的一年一次的觅食回游。 回到河当水位开始在十月落下数目然后慢慢地衰退增加过十二月.(参考文献 12693) 在柬埔寨到 Khone 瀑布这种从正好向上游的金边被报告在此期间向上游移动十月-二月。 在 Kandal 省的 Muk Kompul ，它就在月圆之前溯河回游。 进一步向上游在 Kratie 的附近，迁移发生于月圆而在 Sambor, 迁移在月圆之后紧邻发生。 在 Khone 瀑布的附近，向上游的运动继续过三月，但是鱼正在移动上下两个方向四月时。 从五月到七月, 在那雨季的初始, 它移动向下游的从 Khone 瀑布到湄公河三角州。 在这里，鱼被报告在八月到九月移出湄公河进入管与洪泛区。 当水在十一月到十二月后退的时候，鱼再一次回游到湄公河。 向上游在 Ubolratchatani 的附近在泰国的 Khone 瀑布, 这种在二月与六月之间向上游移动, 主要为稚鱼在二月-三月与成鱼 (15-20 公分) 四月时-六月。 进一步从对泰国的清孔县的在老挝的 Xayabouri 游向上游, 向上游的回游在三月到七月之间发生,第一个藉着稚鱼, 稍后藉着成鱼。 (参考文献 37770) 用来制造了 prahoc 沿着柬埔寨的 Tonle Sap。 在水族贸易中的时常出现.(参考文献 12693)
