Facultative air-breathing (Ref. 126274); Bears strong resemblance to P. bocourti but has different gill-raker counts and coloration. Diet consists mostly of benthic insect larvae and worms, with some free swimming insects, submerged plants and seeds (Ref. 12693). Undertakes upstream and downstream migrations in the Mekong mainstream (Ref. 37770). Length type for maximum size is assumed in TL.
有強的樣似 P. bocourti 但是有不同的鰓耙數與顏色。 食物大部份底棲昆蟲幼生與蠕蟲組成, 有一些游離於水中昆蟲，水下的廠與種子.(參考文獻 12693) 進行湄公河主流的溯河及順流的迴游。 (參考文獻 37770)
