Is blue gourami aggressive? Yes, it’s their nature.


Many fishkeepers consider the blue gourami one of the most visually appealing aquarium fish. Their distinctive and expressive flowing motions and colors set them apart from other fish. Usually, gourami are known to be calm and peaceful fish, but some species like blue gourami can be more aggressive than other species. Blue gourami are aggressive by nature. Males can especially be aggressive and attack or even murder other gourami or other fish species on their territory during spawning when they defend their nest from adversaries.

If blue gourami spawning takes place in a community fish tank, the male may take his rage out on the other fish. If you settled a pair in a separate spawning aquarium, the female would get attacked too. That’s why it is important to separate female back to the main tank after she spawned eggs. Blue gourami can also may attempt to consume the caviar of other fish.

Blue gourami fish are well-known for their constant fighting and being aggressive. Even if there is no apparent need or reason for doing so, they can start fighting. If you place two male blue and pearl gourami from different species in a small fish tank, they can get into fights with one another. Most probably, one of the fish will die in this situation. Violence between gourami of the same species is reasoned by the need to protect a specific territory that is not rare in the animal kingdom.

Aggressive Blue Gourami

When it comes to feeding time, blue gourami are well-known for being aggressive. If other fish want to get the food, too, they will fight them out and then eat it all themselves. Fishkeepers may experience constant anxiety as a result of this aggression each time during feeding. 

What are the most effective methods of dealing with blue gourami aggression in an aquarium? To address this issue, the most effective solution would be to give blue gourami an aquarium with a greater volume. Also, try to add the aquarium with as many plants and decorations as possible so that they have somewhere to hide. If all the above doesn’t work, the only way left is to separate and transfer the most aggressive blue gourami to a different aquarium.

If your aquarium is large enough, include other types of fish as well. This is an excellent method of reducing the aggressiveness of blue gourami. Let me assure you that not all gourami are aggressive and do not always show indications of hostility. It is dependent on the particular individual fish and its specific character. The majority of fights occur between male fish or when there is insufficient room in the aquarium for all fish. However, it would be best to prepare your aquarium well and take into account fish compatibility to appreciate their beauty.
