Fish Being Aggressive

My Mollies speckled is being aggressive to the other mollies what should do when they gather to eat he runs them off. Its my first tank I've had it two months now.

 

Is it possible that the molly is courting the females? Maybe that's why it's aggressive. I believe there should be a ratio of male to females, like 1 male to 2 females.

Ok I think my black Molly is a female I'm not sure or how to tell I name that one midnight...

With mollies and platies, the way you can tell male and female as the male has a stick around the belly area.

 

Females have a fan shaped analfin, males have a rod shaped analfin. Some fish are aggressive in too small of a tank.
