It has long been assumed by most that Asterina starfish only ate the dying segments of corals such as Monti digi and acropora or the algae that were invading a dying coral. I have evidence that this is not correct;

This next pic clearly shows the band of eaten polyps after I removed the star with a large wooden skewer. This was a healthy area yesterday.

They do snack on healthy coral!!! I have a harlequin shrimp to keep mine in check. Mine like the zoas. I even take them from the other tanks and give them to the harlequin, he is so spoiled now he knows I am giving him food and does not run from my hand any more.

I just did a dip today due to these guys. Also have Nudies enjoying themselves on what few corals I have going. If I ever set up my other tank I may have to dip everything before adding.
