Long story short - had to move from the farm to the city (college) unknown to me, my small son had put two baby painted turtles in one pocket, two baby snappers in his other pocket. Got him a tank. Two months later, no painted turtles. A few months later, snappers eating 100 feeder goldfish at a time. One latched on my hand one day while I was cleaning the tank. Couldn't kill it, little boy's pet. Held turtle and my hand underwater until it ran out of air and let go. Shortly after, quick trip to wildlife refuge and release. Turtles probably as big as a Volkswagon by now.
