Another larger family of fishes is the gourami. This species comes in a variety of variations, and the majority of them thrive in freshwater indoor tanks. Depending on the sort of gourami you purchase, you may need a larger or smaller tank if you plan to purchase any of them. For instance, the Dwarf Gourami is a little kind that may thrive in a 10-gallon aquarium. Others, however, have a much larger growth rate and may require a 30 or 40 gallon tank.
The preference for an aquarium with lush vegetation is shared by all gourami’s. Therefore, make sure your tank is filled with tall plants that reach the water's surface. They'll feel at home because of this. Additionally, bear in mind that men don't get along and might be violent against one another. Therefore, just one male and many females should be kept in the tank.
