Now I have TONS of Asterina starfish. They are white with a little bit of grey in the center. This guy is 10x bigger, and brown. He's the only one I've found in there.
Huh.. I have never really had a problem with them, but I'll make sure to keep an eye on them. There are so many, I don't think I could ever get them all out.
No!! The grey ones are bad, they munch zoas. I've witnessed this happen. Orange/brown are fine. I would say that goes back in the tank, it's pretty orange looking to me.
