I do believe he was kidding about that. : If the tank were 60' long, and only 2300 gallons, it would have to be no more than 2' high and 2.5' wide. Somehow I doubt those fish would be comfortable in a very long tube like that... haha. I ran some rough numbers and figured the tank to be something close to 16' long, 5' wide, and 4' high. (also based on seeing a couple arms, the apparent depth of field when panned to the right side of the tank, and the reflections of people shown in the video)
