Okay - leopards are closely related to fat tails, like mine. Like mine, yours have eyelids, which most geckos don't. It is super-cute. Also, you can see through their heads if you look in their ears, which I think is crazy-cakes.
I know they don't need humidity to be as high, but I believe they do need live food, like crickets & assorted caterpillars, dusted with calcium powder - if, like mine, your gecko is nocturnal, you'll want a calcium powder that contains vitamin D3 so they can digest stuff good. Variety of diet is good for your pet, so try to find a pet store that sells not just crickets (whick will be your staple food), but silkworms, butterworms, hornworms, and the occasional superworm

) You want to 'gut load' the insects with healthy foods (carrot, greens, yam, other stuff) well before you feed them. I keep my crickets in a special box for this purpose, a largish plastic box with egg carton & air holes.
As an aside, crickets are smelly and noisy, and I love all bugs generally, but I do not love crickets any more.
Not all calcium powders are created equal... some contain higher levels of phosphorus than are really desirable. Too much phosphorus in the diet will inhibit the animal's body from absorbing calcium, which is why you dust in the first place. I think I use the ZooMed brand... I know I bought one once that, when I actually did the math, turned out to have a calcium to phosphorus ratio that was twice as much phos. as it ought to have been. It's a multivitamin, so I use it in tandem with the calcium D3,and only occasionally.
Here's a page that contains info about the phos. levels of different bugs (it's for beardies, but the info is still good - look at the column for Ca:P ratios, and the comments for different kinds of bugs... ignore the veggies lol, I think leopards are pretty hard-core insectivors).

This is a random leopard gecko page I pulled up that covers giving them hides & setting up their home.

Oh - and if your guy is like my fat tail, calcium sand is a no-go because it can cause intestinal compaction, which can cause death. Moss, larger hides, UTHs and fine coco fiber are all gecko-crab cross-over products.
Edit- sorry I took so long to respond, I habed a bad code this week. Also, now I like this information site better:
