Is the one-inch-per-gallon rule no longer valid?!

Nobody told me... when did this happen?

It uses a linear measure to calculate a volume. It can never and could never
have worked, an I can't imagine who ever came up with a silly rule like
that. A 60 inch fish goes in a 60 gallon tank? Cool.

In any case, it's a metric world these days and who the heck knows what an
inch and a gallon is anyway. Only the US uses that stuff these days
