Sea star ID please

I have always had these in my tanks and they have never caused any problems. The big debate is whether they are dangerous or not. They are a big family of different kinds but I think most reports of predatory members are toward zoanthids not SPS I think.
 
Thanks for that link Cloak.

If I remember right harlequin shrimp eat them if you want to remove them.

Some asterinas actually get rejected by Harlequin shrimp.

An example being the kind which activitly breeds in my 125, despite there being a pair of harlequin shrimp, which often walk over and ignore them. Although some members never heard of this behavior, showing the rarity it's "that" species.
