Hi. I've had my dragon on crushed walnut shells, sand, and currently he's on astro-turf. The sand and shells went in the garbage as soon as i did my own research into the bedding debate. Anyway. He's been on this outdoor carpet stuff for 2 or so years. Its just not working out for us. He doesn't like it cause it tickles his belly, and i don't like it cause of its lack of good sanitation. I was thinking of ceramic tiles. The textured ones. I want to be able to reuse the tank for other things later on, so permanently attaching is not an option. But what do you guys think about sealant? Its non-toxic, i have experience with it, and it looks good. Plus, i can pick it out should i decide. I would think it would make it more sanitary because of its sealing properties. Has anyone had experience with using this idea? Any advice would be nice. Some help with the tile measurements would be helpful. Tank is: 5ftx3.5ft. I don't know if i should cut the tiles to fit at the store, because the dimensions are odd, or try to find precut tiles. Thanks.
