Here are the only shots of our Undulated Trigger. When I bought the tank, I had no idea he was so aggresive. I was going to post these shots as a 'free to anyone who wants him' series, but he died on September 22, 2003.
If you look close at the shots, you'll see that his stomach was huge. He was a digger, always making tunnels, moving coral around, picking at the Live Rock. I think he was eating sand and couldn't pass it. I think it eventually built up inside him and caused his death.
