Have you tyred taking the male out? Put him in a qt tank or a big bucket with a filter or at least an air stone if you can, then rearrange the tank then add the female and the male back at the same time, it could be your male doesn't look at the female like a female just in intruder. If you rearrange the tank his territory is gone and he won't defend it the same. Put them in together so they both claim territory at the same time.
Also if the female is smaller then the male make caves she can fit in but he can't so she can get away if need be.
