Giant gourami community tank will snap and charge any other fish which are small enough for it to bully. Like most aquarium dwellers, giant gourami can be quickly raised with larger, more passive fish. However, if other fish are added to a tank, either large or small, they might be killed within a short period. Gourami tend towards herbivory, preferring algae-based foods, but will eat meaty foods. An algae-based flake food, along with freeze-dried bloodworms, tubifex, and brine shrimp, provides these fish with the proper nutrition while young. Once of significant size, they can be fed legumes, partially or fully cooked fibrous
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
