Are gouramis aggressive?

No, gouramis aren’t aggressive. Gouramis are mostly docile, peaceful fish. They usually get along with members of the same species and various other fish. In fact, most gourami species are great candidates for community tanks.

With that said, gouramis can be aggressive in certain situations. For example, male gouramis can be aggressive towards each other to compete for food, territory, or mates. Gouramis can also show aggression towards other fish when placed in the wrong aquatic environment.

You can prevent gourami aggression by:

  • Feeding them enough food
  • Avoiding overcrowding the tank
  • Providing lots of decorations, plants, and hiding spots
  • Using tank dividers
