Looks like a harmless Asterina Starfish. They stay small their entire lives. They are usually harmless detrivores, but some types enjoy snacking on zoas occasionally. They split in two every three months. So, one makes two, two make four... etc. etc. Eventually they overpopulate and you would have to remove a few. Generally, it's not a problem though...
Good find. Enjoy.
