Most Dwarf Gouramies live for about four years but with proper care can live longer. Dwarf Gouramies are peaceful fish, sometimes they can become aggressive, and they do well in most community aquaria. They are usually found swimming on the middle to top regions of the aquarium. This is not surprising since, like all Gouramies, the Dwarf Gourami is a labyrinth fish.
That is, Dwarf Gouramies can breathe oxygen from the air through their labyrinth organ if necessary. It is important, therefore that the surface of the water be exposed to fresh air. This is usually accomplished by using a hood that allows air ventilation. If you are using good air pumps, this is not always needed, since the air pumps will refresh the air above the water.
