help with an i.d.

[mbrands]

I just noticed this white "thing" in my torch coral. I had noticed a small white ring before, but now it looks like a feather duster. It moves in and out and sort of looks like it is collecting food from the water as it flows. Its tough to get a picture becuase (lucky me) the torch is so open and flowing. If no one can i.d. I'll take a picture later when the torch has closed up.
Thank you to anyone who can help!

This is as close as my camera will let me get and still have it in focus.

Yeah it looks like a hitch Hicker feather duster.

If it pulls in and out, and is more of a fan rather than a circle like a feather duster, I would reckon it might be a barnacle of some sort.
Tend to open and close far faster than feather dusters, and sometimes even move the "fan" according to currents. You may do a search for "boring barnacles" though they are not boring in the excitement sense
