Its one of those roll the dice fish. I've had a blue spot and it didn't touch coral and now a valentini and it has no interest at all. I hear some do though. If you want to be 100% safe don't get one but if you're willing to risk it you can give it a try. My tank with the valentini ony has one sps frag, some zoa's and mushrooms. I'd never stick it in my fully stocked coral tank, I've spent way to much time and money on that coral to have a fish start eating it...lol
