Sorry for the posting over site..it won't happen again. Yes, the total length of this Pacific Eunicid worm was 7 1/2 feet. He was living in the pvc structure that elevated my live rock off the bottom. I had to remove all the corals and all the rock to remove the pvc structure to make sure that I could get all of him. So naturally, the aquascaping changed a bit. It was his living in the pipe that enabled him to escape detection. He would come out at night and eat my soft corals...ricordia, zoos, xenia,etc. and then, back into the pipe. I finally decided to employ some night time viewing to find out why I was loosing so many soft corals....and I discovered ....HIM. After changing my pants, I decided that his removal was a must, even if it meant a total tank disassembly. I figure he came in on the initial loading of live rock two years ago...he found the pipe...and grew. To reach 7 1/2 feet, that meant he grew at about 3 inches a month. This is a Pacific variety, and we all have Pacific rock....so, keep vigilant.
