I try to keep the temperatures at 80 degrees Fahrenheit on the cool side and 90 on the warm side. Since it's summer it gets up to about 95 on the warm side in the afternoon. I keep the humidity between 50-65% by putting a damp towel on top of the screen and occasionally misting. I also forgot to mention that I think he has a retained eye cap from the last time he shed, which was before I got him.
