Hello, today I got a bearded dragon for free, not able to take care of the Dragon at present time but I did get a 20 gallon long, two reptile lamps and screen top. I was wanting to set up a leopard gecko tank and was wanting to know what I would need for the tank. I do know that they do not require a UVB light (is this correct), I was wanting to know what type of heat light, substrate or mat would be best and what kind of food would I need. Thanks.
