about 10 or 15 depends on how big they are
If they are fancy goldfish (the plump looking ones) then 6 or so would do well in an 80 gallon when fully grown if they are common goldfish, then 2 maybe 3 when full grown would be ok as they reach a whole foot long! This may seem like its not many fish for a large tank however goldfish are real poo machines and good filtration is a must.
Goldfish need plenty of room to swim around and get very large. In a 1000 gallon pond you could put 25-50 goldfish just keep in mind that goldfish grow very large and need about 20-30 gallons each when full grown.
20 gallons for one fish and 10 gallon for each addition goldfish. See the related link for further information.
You cannot put any goldfish in a 2 gallon tank.One fancy goldfish needs at minimum a 20 gallon tank on it's own. This is not just because of their adult size potential, but also because they are very messy fish and produce a high amount of waste.

No you schould not have that many fish in a one gallon tank. Thats the size of a big betta bowl. And because they are goldfish it is worse their poops are toxins
It takes 2 or 3 months for a houshold pet goldfish to mature, you can tell if it's a female by that time because they will have some white speckles on their lower fins. Plus, though the common goldfish lives for about 2 days in a bowl, but if you get a 10 gallon tank for it and feed it every morning and night until it's mature, then once a day when it's mature, it can live for a long time; I had a goldfish that I cared for ( the pet goldfish not pond goldfish), and it lived for 9 years! ( It just died :( ) But look for red and/or white spots, split fins, or enlarged eyes as these can be deadly but simply buying medicine from the pet store will save your pets life.

One inch of goldfish per gallon of water is often recommended, so you could keep around 7-8 small goldfish in a 30 gallon aquarium. Keep in mind that as goldfish grow, they will require more space, so fewer fish may be ideal for the long term. It's always best to research the specific type of goldfish you have to ensure they have enough space to thrive.
A goldfish can grow to 12 inches or so. Using the basic rules of fishkeeping which are :- 1 inch of fish needs a minimum of 1 gallon of water. :- Every tank needs a permanently running cycled filter. :- Every tank needs a minimum of 50% of its water replaced every week. It is obvious that a 10 gal tank is not large enough for even one fully grown goldfish. You could put a few small ones in the tank but keep an eye on their sizes and do not go over the 1 inch per gallon rule, otherwise you will have constant sickness/health problems with the fish caused by overstocking.Actually it depends on how big they are if you have a baby goldfish, then you could put around five, but would need to buy a bigger tank later on. ( if they dont die ) If you have fully grown goldfish, then maybe around 2-3. Usually the tank size doesnt harm them. What happenes is that if the tank is too small, then they wont grow and they will probably die. And if one becomes pregnant, then they will have no room to lay the eggs or they wont have enough room to swim while being chases by other goldfish. Hope this helps!
