背棘 (总数) : 0; 背的软条 (总数) : 15 - 16; 脊椎骨: 40. Distinguished from other species of the genus in the area by its count of lateral line scales: 53-60 (Ref. 27732). A large species with very small scales, no barbels, and distinctive coloration. Juveniles silvery with red caudal fin, larger fish with head and body violaceous, rosy, or bluish and caudal fin dusky (Ref. 33488)
用它的侧线鳞片的计数在区域中与其他种的本属区分了: 53-60.(参考文献 27732) 一个大的种具有非常小鳞片 , 没有触须 , 与特殊的颜色。 稚鱼用头部与身体 violaceous 银色的有红色的尾鳍 , 较大的鱼, 玫瑰红色的, 或蓝色的与尾鳍暗色的 (参考文献 33488)
Inhabits large rivers and lowland floodplains (Ref. 12693). Occurs in riffle and deep slow reaches (Ref. 37769). Moves out into the flooded forest where it feeds on leafy plant matter, phytoplankton and insects (Ref. 12693). Migration pattern is markedly different above and below the Khone Falls in the Mekong basin. Below the falls, it makes an upstream migration from Phnom Penh to the Khone Falls between November and February, consisting mainly of sub-adults of sizes 10 to 50 cm. From April to July, it migrates in the opposite direction, from Khone Falls and downstream, constituting mainly of sub-adults up to about 50 cm (Ref. 37770). Above the Khone Falls, from Klong Kaem District, Ubolratchatani in Thailand, fish migrates upstream in February; at Khemmaratch further upstream in Ubolratchatani, it moves upstream in March-April; and at Mukdahan, it goes upstream in May. However, it migrates downstream at Klong Kaem in June-July (Ref. 37770). Only downstream migrations are reported in the Mekong Delta in Viet Nam, constituting mainly of juveniles (2-20 cm), with the smallest fish mainly in June-July and fish between 10 and 20 mainly from September to November (Ref. 37770). From Xayabouri in Laos to Chiang Saen in Thailand, upstream migrations take place from March to August. This appears to be two distinct migrations: one of sub-adults measuring 15-50 cm during March-April and another one of larger fishes of sizes 40 to 90 cm during June-July (Ref. 37770). Not known to persist in impoundments. Individuals caught with dais or traps are often immediately kept alive in fish cages for future sale. Marketed fresh and sometimes dried and salted (Ref. 12693). Known to reach up to 15 kg in Thailand (Jean-Francois, pers. comm. 11/02).
栖息于大河与低地洪泛区。 (参考文献 12693) 出现于急流且深慢的范围。 (参考文献 37769) 游进被水淹没的森林中在哪里它吃叶状的植物，浮游植物与昆虫.(参考文献 12693) 迁移图案在湄公河流域中是显着地不同的上面与下面 Khone 瀑布。 下面瀑布，它在十一月与二月之间利用金边到 Khone 瀑布做成一个溯溪回游, 大小的主要为亚成鱼 10 到 50 公分。 从四月到七月, 它在相反的方向移动, 从 Khone 瀑布而且顺流而下, 主要地亚成鱼构成达到大约 50 公分.(参考文献 37770) 在 Khone 瀑布之上, 从运河 Kaem 区域, 在泰国的 Ubolratchatani, 鱼在二月溯河回游; 在 Khemmaratch 进一步的向上游在 Ubolratchatani, 在三月到四月它向上游移动; 而在 Mukdahan, 它向上游五月时去。 然而，它在六月到七月的运河 Kaem 移动下游。 (参考文献 37770) 唯一的向下游的回游在越南的湄公河三角州被报告, 主要地稚鱼 (2-20 公分) 构成, 最小的鱼主要在六月到七月与鱼在 10 与 20之间主要地从十一月到十一月.(参考文献 37770) 从在老挝的 Xayabouri 到 Chiang Saen ，在泰国，向上游的回游发生对八月的从三月。 这状似二个明显的回游: 在三月到四月与大小的较大的鱼的另外的时候亚成鱼测定之一 15-50 公分在六月到七月的时候 40 到 90 公分.(参考文献 37770) 不知道持续在圈围水域中。 用台或鱼笼捕获的个体紧邻时常对于将来的售卖在鱼笼被保持存活。 在市场上销售生鲜地了与有时乾燥与盐腌的.(参考文献 12693) 在泰国已知了达到 15 公斤 (珍-Francois ， pers. comm。 11/02).
