Why aren male bettas kept in the same tank?
Male bettas are not kept together, at least in small tanks, because they don’t like each other. Bettas have bad vision, for the most part. And anything with a lot of fins that looks like them, typically another male betta, they will fight them to the death. I don’t really know why they do that, if it’s a territorial thing, because they’re in such small territories in the wild, that they defend it vehemently, if it’s a breeding thing, or if it’s a combination of the two. But they don’t like each other and they will fight to the death, so it’s a really bad idea to keep them together. Even in a big tank it’s a bad idea to keep them together.
