Hey, I'm new to keeping fish. I recently got two male bettas and two angel fish. I have them in two tanks( bettas separated). I am gonna get a ten gallon tank from a friend. But I was wanting to know since it is a bigger tank, would it be ok to put both bettas in it without a divider? I am looking at dividers, but i was just curious. And if it would be ok to put a pleco with my bettas.
