While pet shops can be very helpful regarding certain species, chams are their own world. I bought my set up (not including live plants, and minus the cham price of 50 bucks) for 192 dollars. Then I spent another 30-40 bucks on fake and live plants. SInce my guy is still so small, I have him housed in a 2x1x2 ft zoomed mesh cage. In about 3-4 months, I will have to get/build him a large cage, roughly 3 by 2 by 4 for his adult size. As you also have a veiled, you will need similar settings. Be prepared to spend a few hundred bucks to set everything up. The most expensive thing is getting the habitat set up, not the lizard himself. Mine was only 50 bucks, but I spent a good 200 bucks on a cage and lights, and he will out grow his cage in probably 3 months, if that.
Do you know the gender of your baby? Taking care of them can be challenging, frustrating, irritating, smelly, but it can be fun, amazing, more entertaining than tv, and addicting!
Good luck and ask any and all questions here. No question is stupid
Side note- As he is so small, it would be best to start with a smaller cage, so that you don't lose him in the foliage and so that if for w/e reason he falls, he doesn't have as far to go. ALso, you need to know the gender, if you have a female, they can start laying eggs as early as six months, and dealing with that is another world all its own.
