40 g. Fresh tank

Victor,

The way I learned the guidline was as you said it, and also with this
additional advice below:

One of the flaws with the inch / gal guideline is that it fails to
hold true past fish longer then 3 inches. This is because it doesn't
take into account the breadth or height of the fish. If you buy a
fish which doubles it's length when it reaches mature size, it's mass
and volume are cubed.

So, keeping this in mind a 5 inch fish is equivalent to 125 one inch
fish and will account for about 4 gal. of water usage.

Would you say thisis fairly accurate?

There's no hard rule, the typical one is 1 gallon per inch of fish. It
depends on a lot of things, but in general if you have healthy plants
you can have more fish than if you have a non-planted tank.
