Ande,
From the sound of things on Steve's page, his worm ate soft corals, so maybe I'm going to be lucky and not have that worm or any worm other than bristleworms, which I can handle more or less. I can't see a bristleworm killing snails, but I can see them eating snail leftovers because they are detrivores.
I've got muck's trap made and am waiting for lights out. Actually, I'm going to put in my glass jar trap as well, so I'm going to be covered in a couple of ways
The scary and most difficult part is going to be doing flashlight duty because it's not going to be easy seeing the hole of origin in a 120g if the culprit is a worm.
Wayne,
How did you get your worm out of your tank, and how big was it?
