Hello everybody, just wondering if someone can ID this worm I found on the under side of a frag mounting. Thanks, Dan.

I should add it is the red worm in the upper right hand corner of the disk. The other stuff looks to be its young in a tube. So maybe its a tube worm?

More than likely a Polychaete Worm
