The problem is it never balls up it is always trying to lung at where ever my hands are going. The only time I seen this thing in a ball is when the original owner handed it to me. Ever since its been very aggressive. I did cover its head up tonight to clean its tub since it dumped its water every where. It tried to bite me at first when I was moving it to the holding tub. Then when I was putting it back in its tub it got my thumb for a split second. I didnt want to handel it any longer due to the fact that it just ate hours earlier.
