Can someone ID this worm

[Sandyp1]

Lost a few Master Scolys that were doing extremely well. They deteriorated within 3 days. As I removed them I saw this worm. On closer inspection , I found about 5 living in the sand right under the Scolys. Does anyone know what these are and could they have attacked and killed my favorite corals ???

Loos like a bristle worm. Could be a fire worm (ive never figured out wjat exactly a fire worm is). Bristle is Reef safe (for the most part, but def are at the size you have), apparently fire worms are not reef safe.

Those are normal, everyday bristleworms. Whether you want them in your tank or not is up to you, but they more than likely didn't bring about the demise of your Scolys.
