I just ordered some frag rocks since they look a lot more natural than the disks most people use. Most of my SPS corals are mounted to these type of disks via the super glue gel. I would rather mount them on the frag rocks. Would it be bad on them to break them free from the frag plug and remount them to the frag rocks? I think the super glue will break free from the plug pretty easy. At least it does when I don't want it to.
