Feather duster in hammer coral?

Pretty sure this is just a feather duster that rode along with my new hammer colony, but wanted to get a second opinion

Sorry, I'm not able to view this particular video (if you have an still image I'd be happy to have another look).

Sure thing, here's a still...

I don't think it's a feather duster - but I'm not entirely sure what else it might be.

Interesting. It seems to be pulsating in and out of its tube now.

It's probably a barnacle. Check this post out: https://www.reef2reef.com/threads/what’s-living-in-my-torch.836314/

+1 to the coral boring barnacle. I have had 2 in my tank, one on a chalice and the second on a favia. It looks the same in my experience to what your video shows.

Ah, good find. Yeah likely a barnacle. Seems like their worry-level in the tank is debated, so probably best to get rid of it

It will steal food from the hammer. Best bet is to place a Small dab of gel superglue over the opening to stop it
