背棘 (總數) : 0; 背的軟條 (總數) : 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)
用它的側線鱗片的計數在區域中與其他種的本屬區分了: 53-60.(參考文獻 27732) 一個大的種具有非常小鱗片 , 沒有觸鬚 , 與特殊的顏色。 稚魚用頭部與身體 violaceous 銀色的有紅色的尾鰭 , 較大的魚, 玫瑰紅色的, 或藍色的與尾鰭暗色的 (參考文獻 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).
棲息於大河與低地洪泛區。 (參考文獻 12693) 出現於急流且深慢的範圍。 (參考文獻 37769) 游進被水淹沒的森林中在那裡它吃葉狀的植物，浮游植物與昆蟲.(參考文獻 12693) 遷移圖案在湄公河流域中是顯著地不同的上面與下面 Khone 瀑布。 下面瀑布，它在十一月與二月之間利用金邊到 Khone 瀑布做成一個溯溪迴游, 大小的主要為亞成魚 10 到 50 公分。 從四月到七月, 它在相反的方向移動, 從 Khone 瀑布而且順流而下, 主要地亞成魚構成達到大約 50 公分.(參考文獻 37770) 在 Khone 瀑布之上, 從運河 Kaem 區域, 在泰國的 Ubolratchatani, 魚在二月溯河迴游; 在 Khemmaratch 進一步的向上游在 Ubolratchatani, 在三月到四月它向上游移動; 而在 Mukdahan, 它向上游五月時去。 然而，它在六月到七月的運河 Kaem 移動下游。 (參考文獻 37770) 唯一的向下游的迴游在越南的湄公河三角州被報告, 主要地稚魚 (2-20 公分) 構成, 最小的魚主要在六月到七月與魚在 10 與 20之間主要地從十一月到十一月.(參考文獻 37770) 從在寮國的 Xayabouri 到 Chiang Saen ，在泰國，向上游的迴游發生對八月的從三月。 這狀似二個明顯的迴游: 在三月到四月與大小的較大的魚的另外的時候亞成魚測定之一 15-50 公分在六月到七月的時候 40 到 90 公分.(參考文獻 37770) 不知道持續在圈圍水域中。 用臺或魚籠捕獲的個體緊鄰時常對於將來的售賣在魚籠被保持存活。 在市場上銷售生鮮地了與有時乾燥與鹽醃的.(參考文獻 12693) 在泰國已知了達到 15 公斤 (珍-Francois ， pers. comm。 11/02).
