Another large worm ID

[DRoth335]

This is the 2nd type of large worm we found in our 300 tear down. This one broke during removal so the picture is about 1/2 the total length. Included a length picture for reference as well as a picture of its mouth and what it looks like in our QT tank. Any input would be appreciated.

It just looks like a large bristle worm to me. They can get huge.

Agree on large bristleworm. When I switched tanks last June, pulled a 15" one out of old tank
