Here are some clues that might help you sort out the Goldfish boys from the Goldfish girls:

* The female Goldfish are slightly bigger than the males and look even heavier in the abdomen when they are full of eggs.

* Male Goldfish develop white spots on their gills and pectoral called "breeding tubercles" during spawning time.

* Males have midline ridges on their undersides beginning from the back of their pelvic fins and ending at their vent opening. This feature can be absent or smaller in females.

* Males have firm abdomen while in females; the area between the pelvic fins and the anal fins is more pliable.

* Male Goldfish have longer and pointed pectorals as well as stiff fin ray, while females have more rounded pectorals and shorter, finer front fin rays.

* Male goldfish have smaller and more oval anal openings and the anal fins are not as thick as that of the female goldfish who has a larger and rounder anal opening with a slight protrude. The anal fin is also thicker.

* The spawning time is the easiest time to distinguish the boys from the girls. The female opening will look larger and more swollen as the eggs begin to ripen. She would look big and heavier. Since fish reproduce through external fertilization, you can make out when a male is ready by the white breeding tubercles and you can actually push out the milt through his ventral opening by running a gentle finger along his sides.

* There is one more obvious, but kind of time taking way to make out which one of your fish is male and female. Find out who is chasing who - the chaser will be the male and the chased and tired out one will be the female! It's the natural tendency on part of the male goldfish to chase and nudge at a female's rear part.

You may find interesting websites that will propose all kinds of methods: http://petcaretips.net/sexing-goldfish.html , unfortunately, most of these aren't reliable. The only reliable ones require you to see them in spawning condition as adults (around 1 1/2 to 2 yrs old). Males will get tubercles on their gill covers and along the front edges of their fins and the anal opening (vent) will be different between the males and females. There's too much variation between the goldfish varieties and too many fish of unknown ancestry for methods like ridge lines, body shape, fin shape, and the like to be of any use unless the fish are of the same type and you have some experience, or lots of fish for comparison.

There's something to behavior, because males will chase females for spawning, but in the absence of females, they will chase other males. All this will be able to let you know is the gender of the "chaser".

I'm not goldfish expert, but I think during breeding season, the males will get stripes on the dorsalfin.

You can go to the pet store and ask one of the employees, because usually they have to look close to the fish.
