I would wait it out for a little while. On the other hand, I find it extremely odd that the male would kick the female out of anything. The sole reason she is a female is because she has dominance over the other clowns. If you male is dominating the female then it could mean he is changing sex.
There is also the possiblility you are mistaken on which one is the female. It is perfectly normal for a female to want an Anemone all to herself untill the new wears off, especially when the anemone is still small. A small Anemone can rarely handle the beating of two clowns from their rough love.
