asterina starfish. some people claim they have seem them eating zoas. their population will eventually balance out. if you are that worried about them now, send them to someone with a harlequin shrimp.

The coral-eaters are usually pretty rare in home aquaria. Some people have gotten them, but most of them eat algae. If you're seeing it on the glass, overflow, or rock, they're eating algae. I have one in my tank that eats coralline.

I had these in my tank before my recent rebuild. They were on the glass all the time, and found that although may seem mean, if I trapped one or two between my mag-float algae scrapper, they really did a great job at adding a bit more abrasion to help scrape off the green dot algae. Therefor very beneficial as far as I was concerned.

IME the lighter colored ones are fine. The bad ones are dark colored and I have only seen them eating z/p's. Not very scientific but I go by color, or if I ever see them on a coral, regardless of color, they are removed.

Now that's funny.

My buddy with every kind of coral known to man has 4 billion of these little guys in his tank. Not one problem except for insane number size. No reason to panic.

I've heard that about the dark ones, but I've found a few in my tank & they leave a nice clean spot through the coralline algae on the rocks & I haven't caught any on the corals yet. For a while I was pulling the dark ones out & putting them in the sump, but so far it hasn't seemed necessary.
