Your lizard's longevity will be determined by how closely you can match its specific requirements for light, heat, diet, social structure and space. The needs of lizard species vary greatly, so research your individual carefully. Lizards soon develop favorite basking, sleeping and hiding spots. Dominant animals will not share their spots, and visual barriers must be provided for submissive cage mates. Temperatures must vary throughout the enclosure, to allow for thermoregulation.
