I've had a yellow ltplate coral for about a year now. It's around 10 inchs in circ. This weekend it enflated to twice it nomal size and was moving up and over rocks. I've never seen it do this. It has moved 4 or 5 inches to the right or left on the sand bed, but never this far and over a rock. I took pics but alas, I'm very inapt at tech stuff. Has anyone elses ever done this?
