Hey guys! I haven't been on for awhile, but I need your opinions and help anyway. I have a 4 1/2 inch Red Eared Slider (RES). I have had her for somewhere between 3 and 4 years. I noticed the other day that she was missing the last back nail on each of her back feet. I've never really noticed this before, but it looks almost like they have never been there. The skin in between her toes looks like it may be beginning to shed, also. She lives in a 75 gallon tank with a Rena XP3 filter, heater, lamp, UV light, etc. What, if anything is, wrong with him?
