Zero. Goldfish grow to be very large and are big waste producers. The smallest tank for them is 20 gallons, and bigger is better.

Here's the thing about goldfish-- stores sell them as good "beginner" fish, when they're really not.
Goldfish get really big. I'm talking 8-12 inches here, and there's no way you're gonna be able to keep healthy, happy goldfish in such a small tank. A good guideline for fish is AT LEAST 1 gallon per inch of fish, preferably more. Those guys will quickly get too big for even a 15 gallon tank.
I'm really sorry to tell you this, but honestly, the best thing you could do for those goldfish is to give them away to someone with a pond. No one likes being told that they have to get rid of their beloved pets, but those poor fish will be stunted and will die a slow, painful death.
Once you get rid of them, you can populate your 10 or 15 gallon tank with some freshwater tropical fish, like a school of danios or tetras. They're really pretty and active, and look gorgeous against a planted background.
