I guess I didn't mention in my post but the monster in the pic I posted is NOT a bristle worm but rather a 4'+ eunicid worm. Not nearly as common in the hobby as BWs but if you find one, pack up the wife and kids and head for the hills .Greech, back to the important point, how in blazes do you get RID of these things?? and by "spines that can cause permanent numbness" I am assuming you mean cause this to the human who attempts the aforementioned removal?
