I just completed mine. It is a 70G rimless tank. I combined two 3D backgrounds to extend above the tank by about 16 inches. The background above the water has a waterfall, and is entirely planted. Below the water I have 6 Discus, 4 Emerald Corys and 7 Cardinal Tetras. The tank is heavily planted using warm water plants. I used Eco-Complete in conjunction with DAS BioBoxes which contain soil. Most of my hardware is hidden behind the background.
