All my geckos are now adults, as juvis, i used paper towel but as they grew i switched to calcium sand. But i can get regular dessert sand for so much cheaper and get way more for the price im paying. I was looking it up and i read that its bull that calcium sand doesnt impact because it clumps when wet to just like regular sand, but that i should just make sure to use fine partical sand.
Thanks to everyone for ur comments.
