I found a giant worm in my aquarium last night, it is at least 3 feet long, the photo only shows about 6 inches of it at the head. My tank has been set up for about 2 years so must have been in the rock the whole time. The 3-6 months all my soft corals have been disappearing overnight, no fish have been eaten yet, but from what I have read the are vicious predators. Any tricks/tips on how to remove it, would hate to have to break down the whole tank, but I may not have a choice, I don't know how else to get it out.
