I've got my RBTA positioned on a long skinny rock with a leather coral on one end, and a toadstool leather and gorg at the other end. It bounces back and forth along the rock, but never leaves it. The corals don't do well when it stays at one end for a long period of time, but it always moves again. This has been going on since last fall, and the corals have continually grown. Here is a picture of the anemone on its rock.
