Welcome to the forums. I hope you find a good place for support and information here.
Please look over the care sheets here on the forum. They are under the resources tab at the top of the forum. And if you want us to help you tweak your husbandry or make suggestions for a happy healthy guy you can fill out the "How to ask for help" questions that you can find in the Health Clinic. I aways like to fill that out and have others critique so that they can help me catch something that I might have missed.
One thing I would like to suggest is that you remove the substrate at the bottom of the cage. Chams can easily ingest in and cause impaction.
