A small percentage of Asterina starfish DO eat coral. Primarily zoanthids, but they have on occasion gone after other corals. A lot of them are great cleanup crew and do a good job at eating coraline, however they can turn on you. My own personal experience leads me to believe its individuals that get a taste for corals rather then species specific but there are different kinds of asterinas.

Mini Brittle starfish do not eat coral at all, at least I have never read any reports of them eating any. They are a great free member of your cleanup crew.

You may wish to remove the asterinas, you may not. Unless you are losing corals it's not urgent and it can be very difficult to get them all. I was very happy with my massive population for years until a small amount turned on my zoanthids. I've since removed a few thousand but there are still some in my reef.

The white ones generally from my experience they are ok. The ones with the reddish brown colored backs can be trouble

I have seen the asterina on top of polyps, zoa/paly. I tend to take them out when I see them. If you think they are causing an issue I have luck with 2-3 days of blackout and then you can catch them in the open. They seem impossible to completely eradicate.

I have bunches of the white ones, and have not noticed any issues with them eating polyps.
