What will these grow up to be?

In a Bristle worm thread I posted a picture of what I thought were baby bristle worms, but experienced reefers like saltfilmfolks and lionfish confirmed it was wasn't a bristle worm.

Well, of course I find one of these guys come out at night, mostly...Here are some more pictures and a video if folks can speculate what these will grow into and what to do other than nightly siphoning...Thx!

Here's a video...kinda creepy...

Google Phyllodocidae.

lots of scary stuff when I google it....not quite seeing the same type of markings in any of the pictures...I was looking for something with a white band a few segments down from the head...that seems rather unique

Some kind of polychaete worm I'm fairly sure. most are harmless detrivores.

Thanks, hope so!
