Mature male goldfish will have tubercles appearing on their gill plate. This looks like white spot but the appears on the gill plates and pectoral fins.
On males their anal vent tends to concave (sunk in) and on the female their anal vent or breeding tube during mating season is convex (sticking out).
Attached is an image of both male and female, the male is on the left and female on the right. http://www.chinagoldfish.net/text/gongmu...
Hopes this helps.

Well, it is really hard to identify a goldfish's gender. I would suggest you buy 8 to 10 goldfish to have at least one male or one female.
