Well petco said 180 gallon but I don't really think it needs to be that big
For twenty small (1-1.5 inch) Goldfish you should have something like a 30 gallon aquarium.
I would say 50 gallons, but native game fish should never be kept as pets.
it depends on how big it is if it is a goldfish or beta it can be in a bowl.If it is one of those big tiger fish or aqarium fish then put it in a big tank. A fish will grow to the size of the tank or bowl. For instance, say a goldfish is in a tank, it will not grow as big as the tank; however it will grow big enough to be able to swim in their environment. The fish will not overgrow the tank. I had a six inch goldfish in a thirty gallon tank.

No it will get too big
It is classed as a very small tank and could only house about 5 inches of fish. (1 goldfish is a 10 inch fish)
