Sounds like you have a variety of astrina starfish. They stay small, I think the largest variety only gets to about an inch across. Most are just grazers but there are a few species that can be opportunistic.

Sounds like Asterina (see the picture above). The opinion on these is mixed. For some, they're plentiful and harmless. Others say they're predatory, feeding on various corals, including zoas. It could be that there are multiple varieties. In any case, Google "asterina" and you'll find plenty about them. If you want to read an early article on their possible predatory nature, try this article which has been posted over at Garf.org for years: http://www.garf.org/Star/starfish.html
