Jax may get too hot with the Sunglo bulb. I haven't used one so am not an expert on it. A safer bet for jax would be a ReptiSun 5.0. It will produce good levels of UVB without overheating or burning. Also, many montane chams avoid the intense light for more of the day and may not spend as much time soaking up the UV they still need if the light is too intense. You can use an ordinary house light bulb for a basking spot and regulate the basking spot temp by moving the bulb closer or farther from the cage. Put the 2 lights next to each other so the cham gets both exposures at the same time. The UV light will really help your live plants.



A 40 gal tank is not an appropriate setup for most chams, even a single one. Too small, too hard to provide a temp and humidity gradient, the glass is a stressor, and air exchange is more complicated. Don't expect to house them together even in a cage. Unless you have a very large cage (6'x6'x10') the pair can stress each other, the male will constantly pester the female, they will compete for the best basking, drinking, feeding, and hiding spot in the cage and one or the other may end up sick. Chams are loners. They would only share a space during a brief courtship and breeding and separate soon after. You could build a large cage and divide it visually down the center. That way both sides of the cage can share UV lighting, misting, etc. When you want to try breeding you can remove the barrier temporarily. Lots and lots of live bushy plants to give hiding areas, help stabilize humidity, and provide water. Depending on your house climate you may also need to raise humidity with a humidifier. Get a good electronic humidity gauge. You will also need to make sure you can provide at least a 15 degree drop in temp at night.
