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.
有强的样似 P. bocourti 但是有不同的鳃耙数与颜色。 食物大部份底栖昆虫幼生与蠕虫组成, 有一些游离于水中昆虫,水下的厂与种子.(参考文献 12693) 进行湄公河主流的溯河及顺流的回游。 (参考文献 37770)
