So we moved into a new place. Since we were moving I waited to change the RES' tank for a few days because I knew we would be empting it and cleaning it all during the move. Well our smallest turtle starting sitting toward the back of the tank and ignoring us for the most part until it was time to eat. We were starting to get worried because he had been sick and we didn't want him to get sick again. Well tonight we cleaned the whole tank and put everyone back in the tank and he has been swimming around ever since. So for these past few day he was giving us the cold shoulder I find it very funny that a turtle has that kind of personality.
