What is this on my coral

[teresawm]

Was give this little piece of green star polyp and I noticed this little hair like thing moving on it
Any ideas of what it is or should I just take it out of my tank? Only have two polyps on the piece anyway

Looks like the arm of a brittle starfish

agree, that was my first thought too

don't take it out if it is. It's a good thing.

Or maybe not. Just checked out my new star coral and found the same

Those are the arms of brittle starfish. I don't know if those are bothering your coral or not.

Very cool, that's definitely what it is

Yes that's what it looks like and it goes in and comes back out on its own

Are you sure cause it looks like it is in the purple part of the coral
