What reptile should I store in an Exo Terra Desert Kit (Small 12"x12"x12")?

NOthing, that is just mean. its mean to keep anything in a 10 gallon as you cant create a temperature gradient. in a tank that is only 12 x 12 that will be impossible so anything you put in their will be stressed constantly. any thing that you do keep in their has to stay under 4 " so maybe a dwarf sand gecko. Dwarf Sand Geckos a href="http://www.amphibiancare.com/frogs/caresheets/dwarfsandgecko.html" rel="nofollow"http://www.amphibiancare.com/frogs/cares…/a but you should sell that shitty tank and get a longer one as a 10 gallon is $10 and its 20" long 12" wide and 12" high.
