Male and female betta living together.......?

It's the male that is going to be attacked (they're amazons I tell you). If he's lucky he'll only end up with shredded fins. The best way to handle it is to put a clear divider between the fish. Once the male has built a sizable bubble nest for the fry start watching to see if the females show any interest. Definitely don't let all three gang up on him at once.
