Question: How do you build a moss wall in your planted aquarium?

  Options: 
 A. You can build a moss wall in your aquarium by sandwiching a few pieces of aquatic moss between two pieces of plastic craft mesh, just so that the moss fibers are beginning to poke through. Glue it together. Secure to the wall of your aquarium with suction cups. In a few weeks time, the moss will begin to grow through, covering the entire mesh and making a lush moss wall.
