Like all labyrinth fish, the moonlight gourami has a special lung-like organ that allows it to breathe air directly. Because of this labyrinth organ, it is not unusual to see it go to the surface and gulp air. The ability to breathe air allows the moonlight gourami to survive in very low oxygen situations. In fact, if it remains moist it can actually survive out of water for up to several hours. As with other labyrinth fish, these species are oviparous and employ bubble nests
