This is a 1600 gallon tank that was designed and built by Tom Barr for the VP of Esquire magazine. In terms of the overall fish selection, it is similar to what I'd like to see in the 215. However, the Discus shown in this photo are the size of dinner plates (10"), we'll be getting much smaller ones. Check out the Esquire site for video and photos of this aquarium. If you join the BarrReport website, there are behind the scenes photos of the construction.
