Worm ID please
 

http://www.canreef.com/photopost/sho...g-0693&cat=506What are these sticking up ? They don't seem to have anything attached to them when I suction them out during a water change. They appear to be some kind of worm like shell ?

Feather duster of some sort.

Ok to leAve. Filter feeders.

But the feathers never come out. They just sit there sticking up doing nothing as far as I can tell. I used to have a ton of feather dusters all over my rock but they are gone.
