Hm.
I think I agree that the tank footprint is what matters most since it relates to relatively more swimming and hunting area. So regular tanks usually win this vs tall tanks like cubes, columns, etc.
Exceptions to this are freak tanks. I saw a column tank that had rockwork expertly situated all the way up the back wall (vs making the bottom of the tank hold the rock) – tons of swimming and hunting area like a regular tank. It was only 50 gallons or so and acrylic, but weighed like a 120 Gallon due to how thick they had to build it to be that tall.....it wasn't very thick front-to-back either, like maybe 12". Freak tank. There are good reasons (plural!) that most folks don't do tanks oriented like that. It was very cool though.
