ID help needed! button polyps

[Slyguy00]

Just look like a generic speckled green paly to me. Careful with those things, if your new to the hobby you might want to look into palytoxins. Pretty serious stuff. And the greens are some of the worst. Id remove them from the rock before they spread as they will do it very quickly. When removing them make sure you have no cuts on your hands (or just wear gloves)
