I have them set up in a 12x12x12 enclosure with a good chunk of cork bark and a sand/soil mix substrate. 80-88 degree temps, misting every other day. Feeding 1/16"-1/8" crickets and yogurt. They are VERY quick!
When I first get new animals they are inspected completely for any signs of injuries, external parasites, etc. I quarantine new arrivals in a seperate quarantine area. Set them up as naturally as possible to reduce stess, but as simple as possible to allow observation while in quarantine. I use seperate husbandry tools and good hand washing procedures before and after any contact with the quarantined animals. Minimum of 60 days in quarantine before allowing them into my collection if everthing is looking good. If anything is wrong with them, I take proper steps to correct the problem and may extent the quarantine period depending on the problem.
