i just picked up a new female marble motoro a few days ago. and she is pretty aggressive with my 2 other males. one which is bigger than her and the other one is just about the same size as her. she would usually go on top of the males and just tries to like i guess suffocate it. should i be worry for my male rays and my other female ray? they are all marble motoros.
 
I would keep a very close eye on everyone. More often than not that mounting behavior can be rather stressful for the ray being mounted. Over prolonged periods of time this stress can lead to several issues including internals. just keep a close eye on everyone. If you notice any of your rays acting out of the norm or burying itself more than usual it may be getting overly stressed by another ray.
How big is your tank? If the tank is large enough I would like to say you should be fine.
 
this is what happened in my ray tank when the rays starting getting aggressive. and there was ample room and food, no such issues. keep an eye and replace her if she gets too pushy or there could be problems in the long run.

I think you should be ok but do keep an eye, these types of things can go both way depending on the temperament of your rays.
 
When I first got into rays (a few months ago) I started out with a male motoro at 10". A few days later I added my buddies female which is also 10". She was very dominant and aggressive. Mounting him, and pretty much pummeling him even if she was on the other side of the tank. I egg crated divided them, but she knocked it over, and after realizing that he was the same size as her, and that he was a-ok and not stressed, it went on for about 2 more days- then he pummeled her back, and now they are best buds!

But all rays are different, so definitely keep an eye on them. I would suggest separating them for a bit.

Did you QT her at all?
