I have a Starry too, that breed of fish is wild lol.
Yeah I left for an hour and it knocked over the brain coral frag that I haven't secured yet. He's notorious for perching on coral. Also doesn't like hermits or snails near his hole. He carries them out in his mouth and drops them on the other side of the tank...usually right on top of the Favias or Acans. The Tailspot removes small snails from its cave as well in the same manner. Very entertaining fish, both of them. It's like a circus in there sometimes.
