I had a couple that were about that size. only thing i could really say is they dont like being handled and they like to dig ALOT. i kept a little cap of water with them but it was filled with sand every morning so i misted a corner of the tank every morning, not them. i set them free around Phoenix desert area this year. they went from banded like yours to a spotted pattern and their tails got hudge like a leo, id never seen pics of any with tails that big. they are fun to watch. mine got almost 5 inches long. keep alot of safe things they can dig under to hide without collapsing on them. they hardly ever used hides and preferred hiding under or behind something. good luck
