I know the sand looks pretty, but I am currently in love with reptile carpet (which was recommended to me to keep my baby beardie on). It is a stylish green color, came cut to fit the bottom of the tank, and when it gets dirty I can just lift it out and wash it. I know you can get it sized for any tank, so maybe you could use it until they get a bit older.
