Is this a feather duster ?

I woke up to notice this feathery thing growing on my live rock. I believe its a feather duster but not sure. Here a pic.

Looks like a feather duster to me.
Enjoy!
Have you seen it retract?
Try shinning a flashlight at it!

Ok thanks I'll go try that now all are they good to have in the tank? Pretty sure they are but I'm new to saltwater.

They are not a thing. Some actually feed them.

Edited: not a bad thing!

Oh, is it necessary to feed them? If so what do you feed them?

They are filter feeders, you don't have to do anything.
