TB Saltwater live rock worm ID (ITS SO LONG!)

[edmon]

Second worm I saw like this. Looks almost like a bristle worm but it’s not a bristle worm. Anyone know what it is? I attached the video link below.

Looks like a bristleworm to me but could also be a fireworm

I believe it may be some sort of eunicid similar to the one I posted the other day, but this one has a smooth round head (maybe that’s where it keeps it teeth tucked in?). And after watching the video back I noticed it might be eating something, possibly an amphipod since they’re abundant in my tank. I read club soda works to remove them from the rock so I will be trying that.

@ISpeakForTheSeas any idea what this could be?​

It's definitely a polychaete of some kind, but I can't quite see it clearly enough for a proper ID.

Closer up pics particularly of the head from the top and of the parts where the bristles come out (both from the side and top, if possible) would be helpful.

I'd guess it's from the order Phyllodocida, but that's a guess at this point, and not terribly informative regardless.

Maybe this will help? I think they are the same type of worm, it was found on the same rock and there are little grainy structures around the rock I think could have been made by the worms.

This is reminding me how much I still have to learn about polychaetes - I would guess those are separate species of polychaete; for now, I would guess they may both be Hesionid worms (which should be harmless), but I'll try to do a little deeper digging into some of the other polychaete families and see if my guess changes.
