What is The Reason Behind Betta Fish Aggression?
Many people want to keep their bettas with other fish but hesitate because of their aggressive nature. It is known that male bettas will fight each other when kept in the same tank. It can cause the death of one or both fish.
However, it is a myth that bettas cannot live in community tanks. Bettas are usually aggressive with their species and should not be kept with other bettas. They can be aggressive towards other fish, particularly if they resemble bettas.
Bettas also don’t need to fight and kill other types of fish. Bettas can live with other fish, ignoring them if they do not cause any harm to them. But it is not that simple, and bettas will live with other fish only under certain circumstances.
If everything goes smoothly, bettas can live in a community tank easily.

Bettas have flowing fins which can be appealing for some fish, and they can attempt to attack them. So, it is possible that other fish attack first, which results in a fight.
So, you can say that bettas are not as aggressive as they are called. They can be kept with their compatible fish in a large tank. But, it doesn’t mean they are not aggressive at all.
