Another worm ID

[Radar1721]

I pulled this guy out of my tank last night. I wanted an opinion on whether this was a fireworm or just a good regular bristleworm? I don't know if the pic really shows how fat it was. It was like a good sized human finger. Probably around 4 inches long. I don't know if it had anything to do with it, but I had some small zoa colonies that appeared to be healthy start losing numbers.

Thanks

It looks more like a Fireworm to me, but I could be wrong. The link below might help.
