I had the same worm as Steve from Oregonreef. Mine, when I finally got him all the way out of the tank was 7 feet long. I didn't even know I had him. I started to notice softies disappearing on one side of the tank. Zoo's, mushrooms, xenia etc. In the day they would be fine, by morning... gone. Only on one side of a 6 foot tank. I got rid of every crab, starfish and snail I owned. I even removed a yellow tang. No change. I decided to do a freshwater dip on the rocks. As I went to take out the last rock, a very large piece of base rock, I saw something black, about 8" take off swimming through the water. I grabbed a net and caught it. It was a worm that was 1 1/2" wide with some really nasty fangs. I noticed that it had segmented so I took the rock out and broke it up, very carefully removing the rest of the worm. I will swear on a stack of Bibles that this worm was 7 feet long. (including the segmented piece). I was so freaked out by it that I didn't keep it. Of course, I'm regretting that now.
My opinion... if they get to a certain size, they're going to have to eat something more substantial. If corals are whats available, they're going to eat them.
