Spaghetti worms? Or something else...

Just transferred this piece of LR to our new QT atop some fresh base rock. After a few minutes, noticed these tentacle-like things reaching out from those columns of rubble. These are zoomed pics. Can also see feather worm of some kind and side shot of Asterina.

 

iv seen these in my tank awhile back but havnt seen them in awhile so hopefully you find out

 

I think it is a spaghetti worm. I had one in my tank a while back and that's what I was told.

 

I have some to and was told basically the same thing. They never hurt anything and only drag detritus back to the tube so I figuire they are harmless.

 

Thanks for the replies!

I found a Cerith snail with 3 red tube worms living on his shell. Thought that was kind of a strange place to be, considering the snail spends some time under the sand now and then.

 

Those are just mini featherdusters. I have a million of them on my rocks. The white is the calcified tube that variety builds.

 

Yeah, I knew that. Just thought it was odd that a filter-feeder would opt for a mobile home.

 

LOL sorry thought you were asking. I should learn to read better.

 

I believe it is a spionid worm a good member of the clean up crew.

 

After looking up pics of the spionid worms, I believe you are correct. (or chaetopterid perhaps, but I'm not breaking out the microscope...)
