have than the 1.5 gallon tank? A 1.5 has 72 square inches of surface area. What are the dimensions of a five-gallon hexagonal aquarium? And how does one figure the sq. inches in such a space? :)
The reason I ask, and I think you know this, is that surface area (where the exchange of oxygen and carbon dioxide takes place) is far more important than the total gallons or the depth of an aquarium. To figure carrying capacity of a tank, one figures surface area.
Hexes tend to be deeper than wide. Large deep hexes show off fish like angels very well, but because of the relatively modest surface area, one can't put many angelfish into a large hex.
Of course one can always do those water changes like New Guppy Mamma does. I'm not smart enough to do them. ;)
