I have a couple of leather frags that I got form MAAST'ers. They started out as a single finger on a small piece of rock. Now, they are big with many finger on a small piece of rock, and are, of course very unstable.

I would like to remount these onto a larger rock, so they have a stable base to grow larger. But I have a fair amount of flow in my tank, and I don't know any good way to mount them. I can't just stick them in a crevice.

Any suggestions?
