Ok IK that this thread has probably been posted 23472323428473 times, but I really need your opinion. I am on the hunt for the perfect substrate that is affordable, easy to maintain, and looks nice. I know, impossible right? I read somewhere that moss would be good. All you have to do is wet it, place it in the tank, and then let it dry and it becomes relatively hard. Is this a viable choice? Does it mold? The other option I was thinking was ceramic tile, although that doesnt look the best
