This worm has no bristles, and looks smooth with peices of armor on him, he is wrapped around my Goni colony, I think I saw him when I got the colony but just passed it off as part of the Goni skeleton

Ps light just turned on in pic Goni just opening

pick of the head would be useful. @ISpeakForTheSeas
 
There all screenshots of a video, I can post it on a yt short if needed
 
Looks like it could be a large vermetid snail but some better pics would help.

I was also looking up dorvilleidae and capitellid. But I think you got it. This old post tracks too
https://www.reef2reef.com/threads/id-this-worm.360364/
I've seen these (and "Accordion Worms") pop up a couple of times, and I've seen (I think I've even given it a couple times) the Syllis/Syllid ID before, but I haven't found any Syllid species that look like this (most have elongated chaetae/bristles that I've seen).

OP, I would (tentatively, at this point) compare to Iphitime species at this point, as that's the closest genus I know offhand at the moment.
