Well first you want to go to walmart or your local hardware store and pick up 3 cans of krylon semi-flat black. Then you set your tank on its side tape off everything that you don't want painted. Use each can for each coat. Tape on a little piece of background for where your filters hang. That way you won't get scratches. Voila you have a beautiful tank and happy fish. No Flashy background for them to attack anymore. I did it for my 55. I will never buy another background.
