Substrate: Leopard geckos require a substrate that won't hold humidity because they are native to an arid environment. If you're trying to setup a more natural looking environment for your geckos, try using sifted and washed play-sand
diet: It is imperative that young geckos eat a healthy diet. Their long-term health is dependent upon their diet within their first year. Young leopard geckos should be fed five to ten appropriately sized food items every day. The food items should be no larger than the width of the reptiles mouth. This holds true in young and old Leopard Geckos. Adult leopard geckos do not eat as much and should be fed two to three times a week. Throw in about 30 crickets and remove any that are uneaten the next day. Crickets or mealworms should form the bulk of the Leopard Gecko's diet
In addition to the live insects, leopard geckos should also be provided with a calcium supplement. You can gut-load crickets 24-48 hours prior to feeding them to your leopard geckos. Take your crickets and put them in a rubbermaid container and then feed them either chicken feed or cricket food. You can also provide Repti-cal in a dish within the enclosure. The geckos will lick it up when they need calcium. Without a calcium supplement your leopard gecko can quickly develop deformities
