Hitchhiker ID?

Hi all,
Brought home a new Torch last week. It had 7 heads and was easy to split the main branch into two. One went in my 55 and the other in my 80.
I noticed that one head has two "extra" guys that was on one of the of the two pieces. The other piece had one head that had one of these guys.
I'm guessing they are some type of worm. They extend from a tube. They are white, fan shaped, curved to one side and as they extend, they act like a hand that sweeps the water, closes and then contracts.
Photo attached. Two questions...
1. What are they?
2. Are they good or bad?
(If bad, what do I do about them?)
Thanks all,
james =)
