背棘 (总数): 4; 背的软条 (总数): 8; 臀棘 3; 臀鳍软条: 6 - 7. Body is strongly compressed. The back is elevated, its dorsal profile arched, often concave above the occiput. The head is small; the snout pointed; the mouth terminal. The barbels are very minute or rudimentary, especially the upper ones, which sometimes disappear entirely. Color when fresh is silvery white, sometimes with a golden tint. The dorsal and caudal fins are gray to gray-yellow; the anal and pelvic fins light orange, their tips reddish; the pectoral fins pale to light yellow (Ref. 4792). Very few tubercles on the snout which are not visible without magnification; snout length much less than the width of the eye socket (Ref. 37768). Anal-fin with 6-7 branches rays (Ref. 12693).
身体是非常扁长形的。 背部是升高的, 它的背面轮廓弓形的, 时常凹曲上方后脑部。 头部很小; 吻部尖的; 嘴巴终点。 触须非常细小或者不发达, 尤其上面的一些, 有时完全地消失。 颜色新鲜时是银白色, 有时有金的色彩。 背鳍与尾鳍是灰色的到灰黄色; 臀鳍与腹鳍鳍淡的橘色, 他们的顶端淡红的; 胸鳍灰白的到淡黄色的.(参考文献 4792) 在吻部上的少许的小瘤那是看不见的没有扩大; 吻的长度远小于眼插口的宽度。 (参考文献 37768) 臀鳍有 6-7 分支鳍条.(参考文献 12693)
Occurs at midwater to bottom depths in rivers, streams, floodplains, and occasionally in reservoirs. Seems to prefer standing water habitats instead of flowing waters. Inhabits the flooded forest during high water period (Ref. 12693). Feeds on plant matter (e.g. leaves, weeds, Ipomea reptans and Hydrilla) and invertebrates (Ref. 4835). A migratory species but not considered to be a long-distance migrant. Regarded as local migrant which moves from the Mekong up into small streams and canals and onto flooded areas during the rainy season and back again during receding water (Ref. 37770). Some reports indicated that upstream migration of this fish is triggered by the first rains and rising water levels. When it finds a tributary, canal or stream it moves upstream and eventually onto flooded areas. When water recedes, it migrates back into canals and streams and into the Mekong again (Ref. 37770). Often used as a pituitary donor for artificial propagation in aquaculture. Escapees from culture installations have become established in rivers and form the basis for capture fisheries on several Southeast Asian islands (Ref. 1739). Useful in cropping excessive vegetation in reservoirs (Ref. 2686). Used for lap pa (in the preparation of which the numerous small bones are ground fine) or grilled or used to make som pa. Usually marketed fresh and occasionally seen in the aquarium trade (Ref. 12693). A specimen measuring 45 cm TL (2,100 g) was reportedly caught from Dan Tchang Reservoir, Thailand on 8 July 2003 (Jean-Francois Helias, pers. comm., FISHING ADVENTURES THAILAND [mailto:fishasia@ksc.th.com] ).
生存在河，溪流，洪泛区中的中层到深底部水域, 而且偶见于水库。 似乎偏爱静止的水域栖息地取代流动的水域。 栖息于被水淹没的森林在高水位期间时期。 (参考文献 12693) 吃植物 (例如树叶，杂草， Ipomea reptans 与 Hydrilla) 与无脊椎动物。 (参考文献 4835) 一个回游的种但是不被认为是一个长途移居者。 被认为了移动从湄公河的本土的移栖动物向上进入小的溪流与管与在洪泛区之上在雨季的时候而且在水位退下的时候再一次回来.(参考文献 37770) 一些报告指出这一个鱼的溯溪回游被第一个雨与水位上升引起。 当它发现支流 , 管或者水流它向上游移动的时候与最后在洪泛区之上。 当水后退的时候，它游回到运河与溪流与再一次进入湄公河之内.(参考文献 37770) 在水产业时常为人工繁殖取它的脑下垂体使用了。 从养殖设施脱逃的鱼已经在河中变得确定而且在一些东南亚岛上为渔捞业形成基础。 (参考文献 1739) 有用的在修剪方面在水库的过渡植被.(参考文献 2686) 用来了 lap pa(在材料哪一个很多的小骨头是好的) 或烤的或用来制造 som pa 。 通常生鲜地在市场上销售而且偶然地在水族贸易中见到。 (参考文献 12693) 一件测量 45 cm TL(2,100 g) 据报告的标本从丹 Tchang 水库被捕捉, 泰国在 2003 年七月 8 日 (珍-Francois 的 Helias ， pers. comm。, 钓鱼的冒险泰国 [mailto:fishasia@ksc.th.com]).
