I had some of those come with my live rock. They seem to have had babies because they are everywhere now. I can see them on my glass all over. It's pretty cool.
Oh thank god they are feather dusters :joy: I was worried that this might be some sort of aptasia or something when I noticed mine. But new that it could not be as they would go in when I poked them and they seemed so soft looking. Glad to know this.

Yep totally good guys. I have some of those too. pretty little guys aren't they. Some say they can be bad because they can take over, but most say they're good. Everyone I know has them, and none of us have them taking over at all. So don't worry. -ali
