You will need:
Cardboard sheets
Contact paper (there are stone and marble patterns available)
scissors and exacto blade
Cut cardboard to size and cover with contact paper. If you are doing the sides of the tank run the contact all around.
Attach to tank with clear magic tape.
Another alternative is crush/fold aluminum foil and tape to tank dull side up. It will look like a rock wall. You can layer with krylon spray paint if desired for shadow and mossy effects.
