hoping for an ID

OK, yesterday we saw the weirdest creature in out tank. I tried to photograph it but my cheap-o digital camera refused to focus on this little thing therefore I will atttempt to describe.
about 1/2 inch long, very slender crawling up the side of the tank. It was sort of a greenish yellow going into more of a yellowish green. It looked skinny & wormlike with tenicles on it's back. The tenicles were very slender & appeared to change length. Sometimes they moved a lot & other times not really much at all. The front end almost had a pointy nose that would get shorter & fatter as the bosdy moved forward, then the nose would lengthen again & the body would follow. All the time the tenicles are waving around, sometimes in almost a wad on the side of the tank & other times stretched & separated all over the place. I saw no eyes & it didn't look like a nudibranch either. Don't know where it came from or how long it has been around.
I do have something in my sandbed & a few in zoo colonies that has these long, stringy tenicles that it sends out from the middle but I don't know what the middle looks like because it is always hidden. I almost wonder if this was one of "those things" in search of a new home.
Ideas?
Thanks,
Frizz
 
That's it Chuck! It is a Cirratulid! Thank you very much. After reading the description, am I correct to assume that they are perfectly harmless?
Thanks,

Very welcome, and as far as I know, they are perfectly harmless and just mop up (detritus) around the house, hence all the "hairs".

Ha! In that case then I hope it reproduces!
Thanks again Frizz

It is quite common for them to reproduce unless you have predators in the tank that keep their numbers down. Reproduction can be sexual or by fission.
