i think my slider may be developing a mild case (so far) of shell rot. i saw a spot on his belly this morning, & found another on his back when i got home from work. id take a picture but the spots are small enough they wouldnt show up on my camera. can anyone give me some information, im probably going to try to get him into the vet on friday but id like to at least have some idea whats going on & what i can do. im hoping since it seems to be just 2 small spots im catching it before it gets to be too big of a problem
