Hi there,
from the questions you are asking about your cham I get the feeling you didn't do all that much research before getting him. I am not berating you I just want to get you in the right direction. I am listing the most recommended sites for chams below. I also want to ask you if your 5 month old veiled is in a tank as you mentioned below in your question about feeding. 5 months is too old to be in a glass tank - unless you were just calling it that.
You can list your current setup (lighting (brands and duration), food, humidity, menas of water/misting, temps, gutloading, supplements, plants in cage) and we can help you do some trouble-shooting to make sure you and your cham have a long, healthy and happy life together 
here are the sites:
