Snail ID. Good guy or bad.

I found this guy hiding in with some polyps yesterday. I removed him from the polyps to get a picture of him. Does anyone know what he is and if he's safe or not for the reef?
Thanks.

Looks like a Heliacus snail. They wait until lights out and then eat zoanthids/polyps.
