depends on the size of the fish, the filtration, if it is salt or fresh... lots of variables.
A very rough estimate has always been 1 inch of fish per gallon of water.
That all depends on how big the fish are. The rule is "1 inch of fish needs a minimum of 1 gallon of water". The tank could easilly be overcrowded if it is stocked with large cichlids and understocked (if there is such a thing) if the fish are Neon Tetras.
id say 15 fish
length and width for a 55 gallon fish tank
The rule of thumb is usually a gallon per fish, so six gallons would be good. If the fish are on the large side (like a goldfish), then a seven gallon tank would be ideal.
This is simply funny if it really means a fish tank.About 1025.5 for a standard 100 gallon fish tank if the beers are 12 fl oz.Remember fish tank gallon sizes are measured by outside dimensions.
Only 1. Usually a Betta is all that is kept in a 3 gallon tank

depends on the fishes size

The fish are not bad together. But way to many fish for a ten gallon tank. You put one fish for every gallon. They will probly do fine but you will have to clean more.
Depends on the size of the fish, but no more than a total of 17 inches of fish. 1 inch of fish per gallon of water.
you can put a betta in a 5 gallon tank
