Feather duster worm?

[ScottR]

I just introduced a new coral to my tank. Found a few of these small worms that look like feather dusters? Usually feather dusters are quite large so I’m unsure and this is the best pic I could take. Oddly there’s one that retracts everytime I get near as if it can see me. Very odd...

Thanks. Seems like one. Actually I have 4 that I can see now. At my LFS I checked this coral really really well and saw nothing. Usually check for things like aiptasia. Can’t complain.
