Usually the gender of the Dwarf Gouramie is determined by the color of the fish. Most of the time, the males are more colorful while the females are less colorful. At the same time, they are also gray in appearance majority of the times.

The Dwarf Gouramie is a bubble nest builder and you should first have one male with one or more females. Filtration should be kept at a minimum, and there should be no current during breeding. The tank should be heavily planted so there are hiding places and there should be floating plants in the tank for the males to lay eggs under. After a few days, the males should build a nest before breeding takes place. Remove the females after the eggs are all laid and only remove the males when the fry hatches. When they become free swimming, they should be fed infusoria for a few weeks.

The Dwarf Gouramie is best kept in a planted area with other community fishes like platys and tetras etc.
