Found a small turtle one day about two months ago while swimming in a creek. My kids and wife wanted to keep it. So we brought it home. At first it stayed in a small fish bowl, with about a half inch of water and mud. After a week or two we decided to put him in our family fish tank. He has been in here for over a month now, and is really active and happy. It's all water, with a floating turtle pad at top, that the turtle week never go on. The other fish in the tank are still doing good. Ammonia did go up for a scare at first. But it has been steady for the last few weeks. Can't get it to go down to the safe area, but it doesn't go up to the toxic area neither. Usually stays at the top of alert, before alarm. The turtle is eating shrimp in the pictures.
