They are harmless to the coral and will actually protect it from the Crown of Thorn starfish (I believe this is the one) but attacking the stars underside as it moves overthem. As for what they eat I have read everything from being herbivours to eating mucus of the coral or just the bits of food that fall on the coral.

I personally would leave them with the coral as they are a neat addition, and a good score.
