It belongs to the family Osphronemidae under order Perciformes of class Actinopterygii. This species is listed on the IUCN Red List as Least Concern (LC).

Feeding Dwarf gourami

The Dwarf Gourami is omnivorous and in the wild they feed on small invertebrates, algae and other aufwuchs. In the aquarium they generally eat all kinds of live, fresh and flake foods along with freeze-dried bloodworms, Tubifex and brine shrimp. To maintain good health, their diet should be supplemented with live foods such as white worms, blood worms, brine shrimps and quality flake or pellet food. Vegetable tablets can also be offered as well. Generally feed should be offered once or twice a day.

Housing Dwarf gourami

Dwarf Gourami is a good community fish and it has long been recommended as a good choice for the beginner. It requires at least a 5 gallon tank but a larger 10 gallon aquarium is recommended. The aquarium should have plenty of vegetation including floating plants that cover part of the surface of the water. The plants also provide plenty of places to hide. They are usually found swimming on the middle to top regions of the aquarium because gourami is labyrinth fish. The tank should have good water chemistry with pH of 6.0-8.0, hardness of 4-10 dGH and water temperature is between 77°F and 82°F. A regular weekly water change is strongly recommended to keep your fish healthy. The tank should also have an efficient filtration system. In this case air stones are also recommended as they prefer well oxygenated water. It is a good community fish that can be kept with other peaceful fish. Suitable tank mates include peaceful cyprinids such as the Harlequin Rasbora, Trigonostigma heteromorpha and many of the other rasboras, Kuhlii Loach and its relatives, many of the Tetras, smaller catfish like Corydoras species and smaller Rainbowfish. Some of the peaceful barbs also work well but it should not be kept with those fishes that are notorious fin nippers like Tiger Barbs, Clown Barbs, guppies, as well as other anabantoids, including Bettas.

Breeding Dwarf gouramis

The Dwarf Gourami can breed in captive condition.  The male gourami builds a floating bubble nest in which the female lays eggs. The water level of the tank should be reduced to 7–10 cm during spawning and the temperature should be approximately 82 °F. The aquarium must be planted with suitable plant species like Ceratopteris thalictroides, Limnophila aquatica,Riccia fluitans and Vesicularia dubyana. To build a bubble nest the male uses bits of vegetation in its nest. In nature it adds leaves, twigs, roots, peat fibers, and other debris to build a nest. The spawning session lasts for two to four hours and the female produces 300 to 800 eggs. After spawning the female should be moved to a different tank. The male picks up eggs in his mouth and put them in bubble nest and continues to guard the eggs until they hatch. The eggs hatch in about 12-36 hours, but the fry stay in the bubble nest and continue developing. In about 3 days fry become free swimming and leave the nest. At this time the male should be removed to prevent eating the young. Free swimming fry can be fed with infusoria or a liquid fry food until they are large enough to eat baby brine shrimp

Sexing Dwarf gourami

It is easy to make differences between the male and female. The male is much more colorful while females are usually gray. The dorsal fin of male is pointed while in the female it is rounded or curved. The male also has a smaller belly than the female.
