Sounds like male X male anger issues, lol.
I have never seen females fight each other, I also have not seen males fight other females, only try to pin them down to breed them.Also, all the females have been popped by me and two other people, so they are females lol.
Maybe that's what you are seeing and the female isn't ready so she's refusing him."?
I have seen males fight, what you describe sounds just like a male X male pairing.
