Bristleworm or Fireworm???

[Crzyfshldy]

I have googled, watched videos, etc...but I'm still having a hard time telling the difference. I just dipped a coral and these came off. Can you guys help me tell the difference? And are any of these fireworms?

I would like to know too, I have those in my tank. They look like both, pink/red on the tips gray in the middle
