help with removal of huge Eunice Worm

[Myka]

I took one out of my tank a few years back. It was only 11". I knew the general vicinity of where it lived and took apart that side of the tank. Then I squirted soda water in the holes. That didn't work so I did a 50/50 vinegar and water dip...it came out like a rocket and I dropped the rock and screamed like a girl. It had made all sorts of slime coated tunnels under the rocks.
