i got 2 pairs in tubs that are just under 2 ft long they seem to be doing ok in them they have a nice thick layer of red desert sand(the stuff that sets hard when u wet it) and various hides from upturned pots with a small entrance hole broken in it, exo terra hides and caves party submerged in the sand and of cource a chinese food container with a hole cut in the side filled with wet sand and its got wet sand on top to to make it darker and slightly more humid in that particular hide
