You could but it would be alot easier to use the nylon I suggested. All you need do is cut a small piece and wrap in a small piece of shrimp. Tie both ends and place the "trap" near the worm. The nylon will entangle the worms setae and cause it to become trapped. You can then remove the worm without any real hassle or danger to yourself.Johnny E said:Could I soak the rock in freah water until the worm comes out and it not hurt the live rock?
