I purchased a map turle approx. 1 month ago. He seems to rarely bask, but that isn't the problem. His shell is starting to get red patches all over it. I put in a Turtle Conditioner that was supposed to kill the bacteria, but it didn't help. I have been skimpy on doing water changes, so could the buildup of bad stuff be the cause of this? Also, could his lack of basking be the problem? Please help me!
