PNT Shrine

Hi my Pnt seems to have a problem sinking. It seems to swim to the surface all the time and when it tries to lay on the bottom it seems to be struggling to stay at the bottom (like a swim bladder disease). This happens when I feed it. When I do not feed it for a day or two it does not have this problem so i try cut down its diet to the minimal. I feed it a teaspoon of kaytee pellet food for turtles and some turtle sticks once daily. So far its appetite seems ok. What could be the problem? My pnt is about 14cm. Appreciate any help.
