use paper towels as substrate. just roll a few layers down on the bottom of the tank, if your tank is a 20L it should be 3 squares of paper towel to cover the bottom, i use 3 layers for absorbency. Also get a water dish, they should be able to fit in it. get 2 hides, www.reptilebasics.com is a good website for them! they are really inexpensive and made to be reptile hides. get a rheostat and an under tank heater. also some sort of foil or bubble wrap to cover the top of the cage to hold humidity in is good. dont cover it all, just about 2/3 of it.
