Leopard geckos live to be 15 to 20 years in captivity on average, although some survive to age 30. Geckos in the wild have a much shorter lifespan due to predators, injury and disease, which can all be avoided in captivity.
Leopard geckos are one of the most popular types of lizards to own as a pet. They are easy to care for and require a 10-gallon terrarium per gecko for adequate exercise. Terrariums should include spaces to hide and climb, such as stable rocks or boxes. Leopard geckos only eat insects, which the owner should provide once a day for juvenile geckos and every other day for adults.
