its 4.5 (roughly) litres to the gallon,

the "rule" is one inch of fish per gallon. this increases with the size of the fish, so a discus or an angel may be 4" long but also has alot more mass due to its height, so you should alow it maybe 3 gallons per inch.

it also depends on your set up, if you over filter and have an air stone pumping lots of oxygen into the tank, and have a large thank so the volume of water will buffer the water chemisty then you can get away with over stocking a little

Personally I choose to understock as it reduces the chances of water quality problems. The general rule quoted is to allow 1 US gallon of water per 1 inch of adult fish. Obviously this doesnt mean you can have one 10 inch fish in a 10 US gallon tank and some 1" fish dont poop or pee a whole lot so you can have a few more than 10 of them in a 10US gallon tank. The rule is flexible to a certain extent.

Most of the time it works thou, you just have to make sure to research your fish well.
