These guys get a bad rep even though most likely don't eat coral. I understand being overly cautious at times, but ever since I stopped filling my tank with snails and went bare bottom I've had more and more and more of these guys and they actually do a great job of keeping the glass clean. They even clean snail shells too.

There are some that do in fact eat sps. I've seen them wrapped around them munching away. I think it is certain ones however.
