Planning on putting a 180 gallon display( 72"-24"-24") in my dining room (144"-144"). I made a mock up of the tank and display size using some cardboard. It seems kind of big to me. I know almost everyone says bigger is better. I just wondered how much consideration people put into the proportion of tank to room. I don't want to go too small only to upgrade quickly, but don't want to go too big. The first mock up was 30" in width, and even though I would love a 225 it was just to big for the room. Any thoughts would be appreciated. Sorry for the mess.
