i really wanna put some tile and tiny sand to fill in the cracks in my tank. i have a 50g long and i wanna fill it with good, natural looking tile so my tank looks better. so here's my question: how should i go about doing this? do i glue them in the bottom, or do i just place them in and fill the cracks with sand? where do i put my UTH? that's my main source of heat as it is. would i place that in between the inside of the tank and under the tiles, or what? would it heat the tiles enough? would they get too hot? where would i get the tiles? what kind of sand should i get (my geckos are all full-grown)? any other info or suggestions would be awesome. thanks
