FAR more important than time and numbers are the water parameters. Your tank may be perfectly ready now, or it may need several weeks yet. The only way to know is to test the water.

You need to know ammonia and nitrite levels to see if your tank is cycled. If you take a sample to a pet store to have it tested, ask for the numbers. Don't let them just tell you "it's fine." Anything higher than zero is NOT SAFE for fish. You don't need to add chemicals to lower them; it happens naturally when the cycle establishes itself in the tank. To keep your fish as comfortable as you can in the meantime, do plenty of water changes. Once those are both zero, it's safe to add more fish.

You should have a nitrates test kit at home. You need to try to keep the nitrates below 40 for your goldfish by doing regular water changes.

If your tank is that size, yes you can add another goldfish


hope that helps
Good luck

p.s.:
and to the person that said a 5 gallon is good for 5 goldfish???
Your brother is nuts and cruel



Edit*
Nice sized tank, you should be able to keep up to 5 goldfish in your tank
In order to judge when you can add another one, just check your ammonia levels, if they are at '0', you can add one

How big is he tank? You need at least a 40 gallon for 3 goldfish! You can put a new one in whenever you want.

As long as your goldfish are 3 inches or less and you have a minimum of a 30 gallon tank and your water is completely cycled, you can add another goldfish at any time.

Yup, just leave the new one in the bag for 30 mintues sitting in the tank. It give the other fish a chance to see whats going on and it adjusts the new fishes body temp to the new tank water

How big is your tank? If it is a 10 gallon, two or three 2" goldfish is plenty.
