Ive been checking through all the comments and opinions about sand v.s paper towel. Sand can be harmful(can be, not will be) but it provides a natural look on the geckos, easier to scoop(the wastes), and gives them the possibility to dig(which they seem to like alot, in my leos case). Paper towel might be safer, cheaper and easier to remove and clean, but i think it would stress a great deal of the leos by removing them first, then their shelter,logs, stones, etc..., then back again in the tank periodically. Im not sure about the conclusions, but in my opinion sand would be a good enough choice, although you do have to keep a good eye on your pets to make sure nothing goes wrong...I leave this topic open and any other conclusions and opinions are welcomed
