If group-raised bettas fight with each other, they need to be replaced with a larger tank. If the fish tank is too small, they are easy to fight for living space. After replacing the big fish tank, some aquatic plants can be planted in the tank. However, this method only works for Chinese fighting fish. If the breeding is Thailand fighting fish, even if the replacement of large tanks, they will fight.
If put together breeding betta are male, they are easy to fight, resulting in disability. But if the betta fish are raised together as a male and a female, then they will not fight. Therefore, if conditions permit, a male fish and a female fish can also be put together for breeding. However, because the mother fish is not easy to start, so this method is also difficult to implement.
This is the simplest and most effective way to prevent fighting between betta fish in the same tank. Specifically, some baffle plates or nets are set up in the fish tank to divide the fish tank into several relatively independent areas, and only one fish is kept in each area. This prevents them from touching each other and from fighting at the physical level.
