My experience in housing bettas in community tanks
Hey, people I've been hearing a lot of things about betta fish in communal tanks. Trust me I'm all for the rule that if you can resist the urge to out more fish in with your betta you should.

I've even had bettas live with multiple males and not kill each other in a well planted out door pond with koi. The point is bettas are just like other fish. And they can be housed with other fish given the circum stances that you have a healthy happy fish. And yes I've heard the storys of people fish killing other
