Dwarf gouramis are used to dwelling in slow-moving waterways and ditches that are filled with dense vegetation, so they would appreciate a 10-gallon or larger aquarium with slow flow and live aquarium plants. They are hardy enough to survive in areas that experience sudden flooding from monsoons and can live in pH levels of 6–8, temperatures from 72–82°F (22–28°C), and soft to hard water.

How many dwarf gouramis should I keep together? There is a lot of conflicting information because they are commonly sold as community fish and several online sources suggest keeping them in a group. However, in reality, almost all of the dwarf gouramis you see at the pet store are male and they can be territorial bullies. When you put them together, expect a lot of squabbling, chasing, fin nipping, and other damage. Yes, a group of dwarf gouramis might work in a huge tank where the males have space to establish their own space and can’t find each other, but in general, we recommend getting one as a centerpiece fish with other community tank mates.

What fish can live with dwarf gouramis? Even if you only get one dwarf gourami, they are kind of similar to betta fish where it comes down to the individual’s personality on whether or not it can live in a community tank. Some are pretty mellow and won’t bother anyone, some only get aggressive during mealtimes, and others indiscriminately attack any creatures that cross into their territory. If you can find them, female powder blue dwarf gouramis are one of our favorites because they are often more peaceful than males but still have the same brilliant blue color.
