One goldfish can live in a 20 gallon tank, plus an additional 10 gallons per goldfish that you would like to add (40 gallons for 3 goldfish).
This may sound like a lot to people, but goldfish can grow very large, and they are very messy fish which produce a high amount of waste.
You need ample filtration, and regular weekly water changes of at least 50% to keep the ammonia, nitrites, and nitrates at safe levels.

How many goldfish would an 80 gallon fresh water tank take?
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.

Can a blood parrot fish be kept in a 20 gallon tank?
I started off in a 20 gallon tank with my 2 BP, 1 oscar, and a few others, it was very hard to keep up with the water changes as they got bigger. They also faught alot. Now they are much happier in a 50 gallon. the water says cleaner too! So to answer your question, 20 gallons is ok for as long as they are still small and not too many tank mates. But as they say 'the bigger the better'.
