I know this has been posted about time and time again but I thought I would share my experience with making this! I went to Michael's craft and art supplies, where I found clueless employees. I stumbled around until I realize what I want would be under the needlepoint section. I bought 2 black canvas mesh plastic sheets and cut them to fit one side of the 10 gallon tank. It's the side nobody will ever view the inside of the tank from and will introduce enough moss to the tank to make it interesting! It will also block my cichlids from seeing tasty morsels they might wish to snack on. Anyways, 9 feet of fishing line, 4 zip ties, and a lot of patience produced... I don't want to disturb the fishies right now so I'll add the moss and put it in place tomorrow. I also need to stop in again and get some suction cups! That way the fishies won't get behind it and get hurt.
