I am a new owner of an "abandoned and stunted" RES. The girl who dumped him on me, I am finding out, knew nothing. I ended up spending hundreds of dollars on him and I know nothing but have been researching like mad. I've had him since at least May 22. I have his water at 80-82 and his basking area at 90. I have no idea on age so I have been feeding him twice a day. I noticed he has lighter parts on the sides of his shell which I'm guessing means he is growing. I figured I would sign up, post some pictures and see if I could get some guidance. Since I know very little, I am constantly worried about him.

Thanks for everything
