Silver Molly being Picked on..Normal?

[JoshuaTree]

I have just gotten a silver Molly, she is beautiful but i am concerned about my Female Creamcicle lyretail is nipping at her quite a bit, will this stop in time once they adjust to one another? or could it be because the silver molly is roughly 3/4" of an inch smaller than my other 2 mollies??

I have 4 Silver Mollies that hang together and 5 Black Mollies that hang together. Never saw any quarreling amongst them. Maybe get 2 more Silver Mollies, so the 3 can hans together.

well that might have to wait till i can get a larger tank, i was just a bit worried that she might be getting bullied by the other two, it seems to have subsided a lil bit but she still is a bit of a loner for now!
