Hello,
If you could run over your tank set up with us, that would help out.
What type & brand of UVB are you using, a fluorescent tube bulb or a compact/coil light?
What are the temperatures in the tank?
Are you using a bright white basking light or a colored light.
He may be too warm or too cold, which could affect his appetite. Is he eating appropriately sized crickets?
Also, when they shed, many times they wont eat a whole lot as the shedding process can be quite stressful for them. You can try giving a
bath to help with shedding.
