I have an accurate as a hygrometer. His heat source is a 50 watt infrared bulb (the 75 watt made his hot side over 95 degrees). His hot side temps usually stay 88-90 degrees. I always check his underbelly for mites, and nope, still none. His skin is both dull and his stomach is pink. Last night, I put paper to cover his terrarium sides to make it feel more secure. Do you think it might help?
