Can you guys please trim your posts.

it is again, just in case...

Size/cm Fish/1000 cm2 surface cm2 / fish

1 400 2.5
2 110 9
3 50 20
4 25 40
5 12 80
6 8 125

First column, length of fish in centimeters.
Second column, number of that size fish you can have in each 1000 cm2
of
surface area.
Third column, approximate number of square centimeters of surface
needed for
each fish of that size.

Where did this chart originate from?

Dr Axelrod's Mini Atlas of freshwater aquarium fishes, page 715, put forward
by one of the authors, Dr. Cliff W. Emmens.
