Bob, Yes, I have. When I finally moved my “pigs” last year they stopped eating. I think it was the new surroundings also. I had been keeping them in a sweater box ( I only had 2 babies) so I decided to take them out of their new tank and feed them in their former home. It worked just great and kept the tank considerably cleaner. That is the only way I will feed my new group when it is time to move to larger quarters. Have you tried trout chow or Reptomin? Mine love it and I only give fish as a treat. The shells seem to grow better on pellet food. Do you give yours a calcium block? I can’t keep calcium in their tank long as they really chow down on it. I am constantly replacing it. Which kind of db are they? I have a large piece of flat cork floating in my tank for them to bask on. It’s amazing how they can climb onto it with a rock to boost up from. Any photos you can post? By the way, WELCOME to our new group! Vickie
