Croaking gourami finely ground flakes. Freeze-dried tablets may also be fed to older fry. It is important that the breeding and grow-out tanks be covered and protected from cool drafts, as low air temperatures above the water surface may cause damage to the developing labyrinth organs of the young fish when they begin to take gulps of air. Croaking gourami The croaking gourami ("Trichopsis vittata") is a species of small freshwater labyrinth fish of the gourami family. They are native to still waters in Southeast Asia and are distributed worldwide via the aquarium trade. Croaking gouramis are capable of producing a "croaking"
Croaking gourami close to the water surface. At night, they might be found "sleeping" at the bottom, even resting on the substrate (which is not normally a cause for concern), or hovering motionless at the water surface. Like all gouramis, the croaking gourami can breathe atmospheric oxygen from above the water surface using a specialized labyrinth organ (like the Betta) if necessary. It is important, therefore, that the surface of the water be exposed to fresh air, usually accomplished by keeping them in an open-top tank or using a hood that allows air ventilation. If you are using good air pumps, this
