Turtle needs a bigger tank, a 20 gallon size would be better, based on its size. I would give turtle time outside the tank to walk around your house. He constantly is pawing at the glass to get out of the tank. It is cruel to keep it in a tank 24 hours a day. If you got a bigger tank, you could fill it with more water so he could swim around the tank. I believe he would be happier if he could swim around instead of being stuck on the bottom of the tank.
