You know, I was thinking about it, and I think ill be a nonconformist and do neon green, blue, pink, and orange gravel. Ill also add on a outer space background, and fill the tank with glow in the dark fake plants. Ill also add a bunch of those funny little no fishing signs from Walmart, as well as a complete sponge bob decoration collection. Ill top it off by adding an air hose diver and other air hose ornaments, led bubbler's, and ill make the lighting constantly change colors like lights on a dance floor.
