Breeding And Bullying

So i have 3 platys, 2 female (a panda and a red) and one male (bumblebee). The male seems to follow the panda around ALL the time, yet both females seem to have squared bellies... Recently i've noticed the male will attack the red female and relentlessly follow the panda... Should i remove the male temporarily? Any suggestions for stopping this bullying? Also any other suggestions for breeding numbers?

 

I recommend one male for 4-5 females. With that few females, they'll both get bullied a lot.
