my firebellies have wide tolerance ranges for cage setups. I can have all water with plants and an island or all land with a water bowl, or halfway between. the least expensive option I find is a soil brick ($8 or so), a Tupperware from walmart for water bowl ($2-$4), a few fake plants or fake vine from AC moore (no more than $10), and spring water in gallon jugs ($.95 per jug), as well as a 40 watt bulb for light ($3), so total is about $30 for a decent setup
