Hi Kblaix,

Sorry I didn't answer right away, but I was away for the weekend. And my PC keeps crashing while I'm writing responses. Let's hope this one gets through.

You can find just about every bit of information you need to raise a Leopard Gecko from the following URL:

I personally do not use an under tank heater for my Leopard Geckos. I have an above tank heat light (red) that doesn't emit much light, as these lizards are nocturnal and do not require it.

As for what they eat - Meal worms are ok, provided you crush their heads before feeding them to the geckos, as they have been known to eat their way out of the Gecko's gut. I prefer crickets, since this is not an issue with them. you should range the temperatures, as you will see on that site, from 90 during the day to as low as 70 at night.

For younger geckos, I'd use newspaper or paper towel as a substrate to avoid impaction problems. I have all my adult geckos on super fine sand, and I've not had any issues with impaction.

I hope this helps!
