The Chocolate Gourami is a delicate fish that should be housed in at least a 30 gallon tank. It can be prone to bacteria and skin parasites, so good water quality is essential. The Chocolate Gourami prefers a well-established, thickly planted tank, with peat extract. Frequent water changes are a must. They do best if kept in pairs and are compatible with other shy, peaceful fish as tank mates.
The best way to differentiate between the male and female is the yellow border that extends along the edge of the male's anal and caudal fins. The Chocolate Gourami is a mouth brooder that is a frugal spawner. The male and female will spawn on the bottom of the tank and the female collects the eggs in her mouth. She will hold the eggs for 14 days during which time she does not eat, therefore, it is important that the female be in top condition before breeding.
The Chocolate Gourami is an omnivore and prefers both algae-based foods as well as meaty foods. An algae-based flake food, along with freeze-dried bloodworms, tubifex, and brine shrimp will provide these fish with the proper nutrition.
