Chocolate gourami live foods or freeze-dried, frozen equivalents over flake food. Chocolate gourami The chocolate gourami ("Sphaerichthys osphromenoides") is a species of gourami native to the Malay Peninsula, Sumatra, and Borneo. Chocolate gouramis reach a length of . These fish have a chocolate colour with golden bands running down their bodies. "Sphaerichthys selatanensis" has sometimes been treated as a subspecies of "S. osphromenoides". They are restricted to peat habitats. Unlike many other labyrinth fish, which breed by incubating their eggs in a bubble nest, this species is a mouthbrooder. Even more unusually, this species is a maternal mouthbrooder, with the female incubating
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
