I have a question about a tank in Amano's Nature Aquarium World Volumne 1.

On page 26, there's a picture of a 56 liter tank with what looks like well
over 80 neon tetra's. Isn't that far too many fish for such a tiny tank? I
calculate out 56 liters to be nearly 13 U.S. gallons. Is it okay to grossly
overstock a heavily planted tank? If anyone can shed some light on this, I
would appreciate it.
