I was always fascinated by symbiotic relationships. It's part of the reason I got into reefing. So naturally the first thing I bought was a pistol shrimp and a ywg. The first night I came out to take a look and the shrimp was actually on the back wall. He went out, found the goby, and brought him back to his cave. I was so excited. One day I got up and the goby was dead. The shrimp had pushed him out of the cave. As soon as I got a new one things were good again. The picture is from when the tank was new.
