Looks like my roommate has decided on getting her first leopard gecko, an eight month old female, and I'm trying to help her best I can. I've owned and cared for snakes for a few years now, but have no experience with any other reptile. This will be her first reptile. We've both read over the care sheets and have a few questions before she purchases. The gecko will be in a 10 gallon tank for a few months and upgrading to a twenty when my boa upgrades. She's a pet as of now, don't think either of us plan on breeding at all. 1. What's the general preferred method of heating? We have access to heat pads and heat lamps. All will be regulated with reliable thermometers and a dimmer. Also have a reliable reptile vet in the area. 2. Substrate? We're being given a piece of reptile carpet for now. Wanting to avoid sand. I saw a bag of "river stones" at the pet store marketed for small turtles. The size of the stones looked to be about the size of my thumbnail. Would that be okay by itself as a substrate? 3. Are crickets a necessary prey item or can you vary between like the different worms listed on this site's care sheet? We've been told her favorite foods are wax worms and meal worms. This is her, not sure on morph so any guesses/confirmation would be appreciated!
