Ok I have 4 male betas and 12 females. If I have a decorated 750 gallon tank can the all live I'm harmony! ?

I've tried all the males in a much smaller tank and there's one big boy that's kinda bossy but is too busy puffing up to swim after the other three and catch em. The other three don't mind each other at all and no one ever bites even when blues in there (the big male) all the females get along great so would this be an ok move?
