Betta fish are known to be predators in their aquatic kingdom. They’re also called Japanese fighting fish, thanks to their aggressive nature to other fish. Therefore, it’s commonly recommended that you keep your bettas in a separate tank.
However, your lovely pets don’t have to swim through their life lonely forever.
