I agree with Amanda on all points.
Yes, the fish in the first post was a barb as 1077 correctly said, but the photo in photobucket is a blue gourami as subsequently identified. This could be the centrepiece for a nice tropical tank. But the goldfish is not suitable in such a small tank, so I would seriously attempt to have it re-homed--another aquarist, or someone with a garden pond, goldfish can live happily year-round in a pond even when it freezes over (so long as it doesn't freeze solid), or a store.
Water changes should be done weekly, once a week, and the volume depends upon stocking and if there are live plants. Won't get into all this until we know more what you plan.
And a belated welcome to Tropical Fish Keeping forum.
