I agree. I started w/ the carpet, but found my sub adult leos catching their mouths on it while hunting. I used paper towel successfully & now have tile in my tanks. It looks great & was really cheap! The 12x12 inch tiles sold in home improvement stores fit perfectly in a 20 Long. You'll need to buy 3 & have one cut, so you have 2 full & one partial piece (measure the inside of your tank before shopping. the store will cut the tile for about 25 cents per cut). The whole project was about $4.
