Additions have been made to our tank. A water bed is the biggest change which we made. This was added to help clean the tank because recently we have had very filthy water. Our turtle has a very bi-polar personality. One day he'll be swimming around everywhere and eating really fast, but the next he'll lay almost motionless barely eating anything. Our tests are all stable and nothing drastic had happened. We have not lost any fish and i think they will all survive until the end.
