Starfish ID

Can anyone tell me if these are good or bad for a reef aquarium?

They were hitch hikers on a piece of coral. I believe I removed all of them, but I'm not sure.

The ruler is upside down in this picture, units are in inches:

Thanks...

I found some in our button polyp also. Except they were silverish grey. We left them. Mainly because we can't get to them...lol..I thought they were ok but don't quote me on that.

It is a brittle star. I have estimated that in my tank, there are 300 brittle stars.
