Friend or Foe?

Foe, get rid of it. They reproduce very quickly.

The white and grey Asterinas are ok, the ones with some coloring in them are the bad ones. If you look closely at the pic above, you can clearly see the coloring in the starfish.

I didn't look at the picture very close. Thanks for the clarification!

I think I have the white and gray ones. Haven't seen them eat corals. Yet. I pull them off the glass when I see them. I'll be getting a harlequin shrimp.
