Need help with a hitchhiker worm ID

[Cryzid]

We are relatively new to the hobby and are setting up our 50g again after having had to tear it down for a move 2 years ago.

We are mid new tank cycle (diatoms galore) and have found a worm in one of the new live rock pieces we have seeding the tank. We can't seem to ID this guy and were wondering if anyone here could point us in the right direction.

We've found similar'ish pics online but nothing that close enough in color and shape enough that I'm confident in a match.

Thanks ahead of time for any info.

Also...we've seen 2 inches exposed but never the whole worm and we only see him when the day lights are on.

I had 3 of them in my 125, would find entire zoa colonies disappear over night
