What you have there is a turtle. It needs water to survive. Someone more experienced with turtles will see this and help out soon. Good luck to you.
Your water turtle isn't 'living' Mrs. Fuchs, it is merely surviving and slowly starving to death. Water turtles cannot eat unless they are submerged under the water. They can't swallow without the water. We are telling you the truth. It is a female water turtle and needs a pond in order to thrive. They don't eat grass or foliage, they eat bugs, worms, fish, etc.
I'm looking at the book we got when we got this turtle. My guy doesn't have webbed feet. So if he is a turtle, then wouldn't he be a terrestrial turtle? or at the most semi-aquatic?
