Pipe Organ Hitchhiker?

[PhilTheFish]

I just purchased this pipe organ last week. Seems to be doing great in my tank so far but I noticed a little hitchhiker the day after I got it when I was feeding my tank. It looks like a worm with alternating bands of color (white and purple possibly). I dipped the coral for 10 mins prior to putting it in my tank so whatever it is survived that process. I know not all hitchhikers are bad so hoping someone can help identify this so I know if I need to dip again or not.

Looks like it may be a brittle star arm.

Thanks! I also just noticed that clear tube like thing above where I circled is alive. I thought it was some debris lodged in there but it's moving around and opening and closing. Is that a part of the coral or another hitchhiker?

Can't tell for sure what that is. Sorry.

That's a solitary tunicate - a harmless filter-feeder.
