You cannot set such a vague "rule" when there are way too many
variables when it comes to stocking a fish...much more than it's size
in inches.
======================
Such as the fact a 1" goldfish passes a lot more waste than a 1"
guppy.

The rule was for tropical fish, not coldwater.

Doesn't work there either really. A six inch Rainbow fish is a lot more
mass, and a bigger waste producer, and requires more tank, than 2 or 3
neons...
