My dream Tank would be a 20x20 room with a 36" wide tank lining all the walls(roughly 4155G), leaving maybe 6ft open in the middle of one for a doorway. I would want it set up on a drip system. Substrate would be large river stone gravel with powerful undergravel filters. I would have Monster Driftwood through-out the huge tank with the occasional nice looking fake plant. I wouldnt stock with any huge fish, but I would have a helluva variety of SA/CA cichlids with my fav oddballs like bichir, Knives, and schools of knuckleheads like Tinfoil Barbs, Silver Dollars and Balas. The room other than the tank would be empty except for tank length benches lining the tanks.
