haha! I see no future as a worm hunter! I'm embarrassed to say how long it took me to go hunting for this one after suspecting I had a problem and I *really* don't want to do that again

Not to make you worry, but I'm pretty sure that eunicid worm didn't come in on a piece of live rock. I can almost guarantee it didn't come in on the original live rock. *shiver* Next rock will be definitely be dry rock!
