Male guppy

I’ve got a male guppy in my community tank who is a lovely colour but he is pestering and bullying my female platys. I’ve tried everything recommended separating him for a few days but he hasn’t stopped. I have no female guppies which is possibly why he is behaving this way but I’m at full capacity so can’t add more fish. Free to go to a good home where he can mate and not pester my platys
