The 20 gallon would be best, without a doubt. Three small goldfish in a reasonably maintained 5 gallon would stay healthy until the switch to a pond. Naturally, you need to keep an eye on water quality. Ammonia can build up quickly in a goldfish tank. Feed carefully and do your water changes. Goldfish will get red veins in their fins when ammonia levels are dangerous.

If you wanted to permanently house your goldfish in an aquarium, the bigger, the better. Be observant, do some research and you will gain an intuitive sense as to what you need to do. The main thing is to enjoy your hobby with mutual consideration for yourself and your dependent creatures.

I actually have to disagree on this. Simply because of size. Building a pond takes a while and is usually done in warmer weather. Goldfish grow fast, and in a month or two they will outgrow the room in a 5 gal. With sufficient water changes the water could be kept clean enough, but due to the growth rate, they will soon simply get too large to be comfortable housed in such a small area for that time.

Getting the goldfish to the 20 gal as soon as possible is their best chance. However, if you can find a huge plastic tub that is larger, that would be the best solution.
