I wonder what this could be?

Found this worm in my 20 gallon tank I'm trying to tear down. Just wondering if anyone knows what kind of worm. Thanks in advance!

Weird bristleworm!
I just have the common ones where the bristles aren't all wavy and colorful like that.

Some types are bad and, I think, the experts (not me) like to see pics of the head/mouth so maybe try to get a pic of that?

Worse if its a bearded fire worm. Those eat coral.

So I found the other half that broke off. I think it's a hobbit worm now. That black thing in its mouth ate pincer like jaws that were open and closing
