Im curious to know if anyone here keeps uromastyx (spiny tailed lizards). Im planning on getting by the end of march and i'm hoping someone here will be able to give me some tips.

The humidity in my rep room is 50% so would the basking light be able to lower it to 30%? is lower than 30% acceptable?
How big of a water dish do they need?
Do they need a hide on both the basking end and on the cool side?
Is a mixture of sterilized play sand and peat moss and acceptable substrate?
How often do you feed crickets or mealworms and how often do you dut their veggies?

Sorry for my bombardment of questions but id like to be as prepared as possible
