Is the one-inch-per-gallon rule no longer valid?!

Nobody told me... when did this happen?


It happened quite a while ago.
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.
Things one needs to consider are of course the adult size in length,
but also mass makes quite a difference. Waste output is different with
some species. Territory requirements.
Just because a fish may be on the smaller side, doesn't mean it's not
going to shredd another fish that comes into it's territory, but was
the right size in inches for the rest of the space in the tank.
Dietary needs, temp, water chemistry, lighting, etc.
All of these things need to be coinsidered when stocking a tank, not
just how long the fish will grow to when it's an adult.
This is why it's not valid.
