One of my 10 gallons is an oriental theme, plastic bonsai tree, pagoda's etc. My other 10 is a sunken ship, sharks(ceramic) and a no fishing sign. My 75 is story book fairy tale... complete with huge castle, rocky mountain, dragons, a bridge (the only troll under it is Polly my Pleco) and a "forest" of plastic plants of all sizes (not enough light gets in for real plants).
Use your imagination and make a cool looking tank.
