Someone earlier was comparing a 4 ft by 2 ft, 120 gallon with a 6 foot by 1.5 foot 125 gallon, saying a footprint (bottom area) of 8 square feet versus 9. That is mathematically correct and sounds like not much difference. However if you look at the diagonal bottom distances, the 120 gallon has a 4.5 foot diagonal, the 125 has a 6.2 foot diagonal. The 125 gallon tank, has a whopping 38% bigger diagonal than the 120. That is important to me, as fish who need space from other fish for whatever the reason, appreciate the ability to isolate.
I used to own a 180 gallon tank (6' x 2' x 2' tall). I sold it when I developed my T.V./Entertainment room. I later got a 135 gallon (6' x 1.5' x 2" tall) for another room. I miss my 180 somewhat but it was so heavy to move. In this case the floor diagonals between the two tanks are less than two inches (75.9 versus 74.2). I know I could fit more fish in the 180, but six frontosas in either tank would not make that much of a difference.
