Does floor tile give a lot of heat? I want to get a tile substrate for my leopard gecko, but I don‘t know if it will get warm enough for him. I have an under tank heater, so if I put the tile in will the heat from the under tank heater block or go through the tile?
Yes, tiles are great. The tile will retain heat, so that's even better. Leo's are found on hard clay in the wild so tiles are the best replica.
I put a little layer of sand under my tiles to fill up any air spaces under the tiles (as they're textured to hold grout). Tiles heat up and hold heat a LOT better than pretty much any other substrate. If you want some really neat tiles, try slate. They are really natural, come in awesome colors naturally and hold heat just as well as other tiles. But there are some really nice ceramics, too. Just don't get anything overly glazed.
