At A Loss

[bellabean]

I'm at a loss of what to do!

I have a very persistant male mikey mouse platy .
We have him and 2 female platy and 1 female lyretail. Well my poor red swag female is just the centre of his attention. He won't leave her alone! There's hiding spots but I swear he seeks her out and is always side by side. She is forever trying to get away. She eats and all that no problem. Today I noticed the sunburst female was being bothered by him but she kind of swam away. If she got close he darted at her!

What do I do?!
My only other tank is a 5.5gal for the babies.
Or do I let them be

I have a very persistent MM male too
He has 3 females, but he harasses one in particular.
She's smaller than the others & spends a lot of time hiding from him.
I may put her in with my guppies if he doesn't give her a break
