Facultative air-breathing in the genus (Ref. 126274); Its natural habitat is described as mostly soft water backwaters in which there are no water plants although the banks are overgrown with Pistia or Eichornia. Branches extending below the surface and driftwood on the bottom serve as surfaces that the fish can scour for aufwuchs and this fish can actually scrape off some of the wood itself as an aid in digestion (Ref. 6868).
虽然浅堆长满 Pistia 或 Eichornia ,它的自然栖息地被描述为大部份软的水洄水区在那一个有没有水中植物。 向下延伸在底部上的表面与流木的分支当作鱼能为附着生物拭磨,而且这一个鱼能实际上作为一个消化的帮助刮掉外海的一些木材本身的表面使用。 (参考文献 6868)
