No skill required, like any animal, its all in your setup. Proper Husbandry = healthy happy animal. When an animal is said to be better for experienced reptile owners it is only a commentary on the fact that the reptile is not as forgiving when you dont provide proper husbandry.

A cham set up if done properly is very low maintenance. I only break my cage down once every moth or two and have a large water container for my drip system so I only have to clean and refill it every couple of days.

About the only thing I see people goof on is not giving proper lighting. I recommend a 3 bulb system... One Desert, one Tropical, and a UVA basking bulb. The combination creates a full spectrum of light that allows the cham to see properly and gives not only a heat gradient but also a UV gradient so it can manage its own exposure.

Despite what others will try and tell you, dont trust a tube florescent light bulb and more then a compact florescent. Both have the ability to output improperly. Only way to be sure is to use a meter to test out how much exposure your animal is getting. Not using a combo of bulbs to provide a more complete spectrum dose effect animals like chameleons and iguanas.
