So does anybody here have a tiled bottom in their ray tanks? Im a big fan of smooth barebottoms but Im considering laying tiles on the bottom to make it more visually appealing and possibly, even more smooth for my rays to glide across. Anybody with experience on this have any tips? What type of tiles should I use? Should I silicon it down or just lay it down? Im worried about crap and debris getting trapped under and in the sides on the tiles and messing up my water. Im also thinking about using tiles with bigger surface area so theres less cracks in between for debris to get stuck in, is there any sort of disadvantage? Thanks.
