Whats on my LR?

[RockingCricket]

Can anyone tell me what the tubeworm like, feather duster style critters might be that came on a piece of live rock that I recently purchased? They look like white little eyelash fans which are unfurling out of tiny holes in the rock every few seconds.

My guess is some sort of spaghetti or peanut worm--whatever common name works for you.

if they look like eyelash fans i would say they are some sort of Sabellid or Serpulid worm, beyond that its tough to ID these things...certainly not bad though
