My pair is housed in a zoomed 12x12x18 and they seem fine. It's a little small but they make do. I switch between eco earth and paper towel substrate. PT is when I think she's getting close to laying eggs because they bury them and it makes it a real bugger to find. Babies should be kept on paper towel. These guys lunge for food if it's live and get substrate ingested.

I'm more of a snake person, and cresties are the only lizard I will keep. They are so much fun. You won't be disappointed.

A good base of CGD is needed as crickets (even gut loaded or dusted) do not provide the nutrition of pure diet. Some people I know feed crickets once a week, I feed crickets less than once a month. Eventually the gecko will get more of a taste for diet and start eating very few crickets. The downside to these guys is they are so prone to Metabolic Bone Disease (MBD) without using CGD.
