Leopard geckos are found in southern Asia, in India, Pakistan, Afghanistan, Iran and Iraq. Leopard geckos inhabit arid regions, particularly rocky deserts and sparse grasslands. They avoid sandy deserts. They are strictly nocturnal, keeping out of the heat of the day, emerging at night from holes and crevices to hunt for food. In the wild they mainly feed on a variety of insects, including scorpions, but will also eat other lizards.
Animal often live in loose colonies.
Leopard geckos are seldom found off of the ground. A single animal can be maintained in a ten gallon aquarium with a paper substrate. If you prefer, they can be maintained on reptile carpet, gravel or orchid bark. The use of sand as a substrate is not recommended for leopard geckos. They will occasionally ingest too much sand in their craving for calcium or accidentally during hunting activities, causing a sand impaction that could become quite serious.
