My wife recieved a juvenile male for Christmas. We have him in a 45 gallon tank with plants, vines, and logs to climb on. During the day, we use a 65 watt heat lamp, USB light, and a light strip. At night, we have a 100 wat ceramic heat lamp for him. We have a misting system and a drip waterer. Although I have only seen him eat one cricket, they seem to be disappearing from the tank. The floor is a reptile substrate. While sleeping, he turns a light green with yellow stripes. In the day, he's a dusty gray with some rust color. I'm worried about him. Any advice is appreciated.
