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.

Not really. I doubt one 5 inch fish will eat as much as 125 one inch
fish and thus produce 125 times as many poop. You can't just extrapolate
with living organisms.
Besides, the ammount of poop produced by a 5 inch pl*co is quite
different from that produced by a 5 inch Kuhli loach.
