Well guys thanks for the help, but Taddy has died. He some how wedged himself under the rocks in the tank and got stuck. When I found him he was dead. He was acting really weird. He was on the bottom of the tank on his back part of the time, swimming like normal some of the time, and othertimes trying to climb to the bottom of the tank. It may have been part due to changing the tank. We have a small tank and I know that doesn't help either. Thanks for the support!
