Help identifying little white starfish

I just got home and found a really big one (almost 1" across) crawling across a colony of zoas. I got really scared and though "How ironic, the same day I do research and figure out what these guys are is the same day I see one eating my zoas." I've never had a problem with them eating zoas before!! Luckily, it turns out he was just taking a stroll through a green pasture. All OK!
