This is not like my usual bristle worms...ID please

[AkaSlyGuy]

Found this guy in my new refugium that I have set up on a new tank. The sand came from my old tank that I am going to tear down this weekend. I decided to only use the old sand (ootlic) in the refugium. I added about 5 inches and found this guy the next day. Any ideas??

Fireworm?
If so, hurts more than a bristle worm!
Be careful.

Looks like the rear end of a lumbrinerid polychaete. They are predators on smaller worms & will eat detritus as well.

Humm, that is interesting. Anyone else seen one of these before?

It looks similar to what I found underneath my brain coral. I lifted it to find two long bristle looking worms that were mostly pink and when they slithered away they had a rainbow shine as they moved. They were mostly redish pink though so I assume they are fire worms.
