I think you have a Serpulid feather duster.  It doesnt have the feather duster thing but rather, has a jaw like thing that lets out a spider web.

 

There are many colour forms too, from red-pink-brown-white.  

 

Have a look at this link;

http://www.reefs.org/hhfaq/pages/main_page...s/faq_rock3.htm

 

Scroll down to  Serpulid feather duster and you will see a pic and info about it.

 

Plus the page has lots of other useful and interesting critter info.

 

Hope this helps.

Try a web search for vermetid gastropod.  Sounds exactly like what you have.  A sessile snail, lives in a tube in rock.  When water is cloudy & full of particles, the worm sends out a mucous trail that collects the particles.  Then the worm reels it in.  Totally harmless to reef life...beneficial hitchhiker.

 

Have fun!
