what is this...

Found something living in what appears to be a small tube, kinda long, inch or so growing on the LR. Has this thing that I thought was a Feather duster when I first saw it but then when I was checking it with my mag glass it 'tarted' inside the tube! Here is the best pic I could take, it's tint and @ around 4 o'clock to the top hole on LR.

It looks like a mini tube worm. They are very common hitchikers on live rock.

Tube worm with feathers LOL Good or Bad? I see what appears to have been more of these that have died and the tube left and is white.
