Well I know I've heard people say that you don't want to let any of your rocks touch or lean on the glass, and I don't. But I have this small 3-4 pound triangle shaped rock, and to put it where I want it, I would have to let the top point of the "triangle" lean on the back glass a little bit. I don't think it would be very noticeable, but I don't think this would cause a big problem.
