Well, when I first pulled him out of his tank, he looked really gray near his eyes (which he didn't look that way when I got him). I pulled him out of there and let him soak for about 20 minutes and his color came back. I was just curious if UVA can be harmful to them? Because I use a 50w UVA Bulb for his day light cycle and I want to make sure it will not burn him or anything since they have sensitive skin.
