My nephews found a tiny sun turtle in their yard. He was only the size of a quarter. I somehow ended up adopting the little guy/girl..... well it's been over a year now and he's getting big and out growing his plastic reptile tank. I've been thinking about letting him go into the lake in back of my nephews house, which is probably where he came from. Would he be able to survive after being sort of a house pet all this time???
