Help! Tiny pest starfish damaging LPC

[rbjone1]

I have an over run of these tiny starfish that are attacking some of my corals. Right now they are eating the pipe organ and chili sponge polyps. They fragment so that often they are segments of two or three appendages. They are about the diameter of a pencil eraser. Identification and control suggestions:confused?

The Asterina starfish being a controversial subject are often confused as predatory; they are primarily Coraline algae feeders but also munch on dead tissue. A Harlequin shrimp will make a good meal out of them.
