I've been keeping the humidity at around 60% and his eyes have started to smooth out since I've had him, but he still still has little creases. He's about three feet long and I don't know when his last shed was but like I said, I've had him for about a month and when I got him there were little pieces from his last shed scattered around so I don't think he shed properly whenever he did. From what I've read I'm assuming that that was because he was kept too dry?
The warm side of his tank is 90-95 degrees, and the cool side is 75 degrees. He has a hide on both sides but he usually stays on the warm side. I've been keeping the humidity up at at least 60% to try to help his eyes.
