Keeping different size rays together

[African_Fever]

Just wondering what everyone's experience has been with keeping different sized rays together. I'm thinking about getting a new ray or two, but they'll be about 4-5", whereas the two I currently have are 9-10" (all will be motoro variants).

Are there any aggression issues to worry about with keeping different sized rays together?

I did this before a few times.... first time no problems last 2 times had to be seperated.... I would either go for larger rays or get a 40 breeder and tie it into the tank the larger rays are in for grow out...
