Your library and pet store should be able to help you research the natural history of the species you keep. Create a captive environment that is not only beautiful, but easy to clean. A double set of pebbles or small stones means that one set can be washed and disinfected carefully, dried and stored ready for the next cleaning. Use a substrate that will not be accidentally swallowed during feeding or exploration.
Small items can cause obstructions if they stick to food and are swallowed.
Provide heat in a sensible form. Climbing reptiles will not get much benefit from an undertank heater, especially if the bedding insulates well. The reptile will need heat at night as well. Use at least two thermometers in different areas of you enclosure to determine the ambient temperature. Block part of a screen top if you need to retain more heat or humidity.
