A goldfish's gender will be very hard to determine before the goldfish is three years old. After this point, the male will develop little white pimple-looking things on his gills. These are called breeding stars. A female's fins will be more rounded and her tail will be convex.
The female has a larger butt. This is the best way to tell a female from a same sized male.
The female goldfish has a fanned fin and the male has a fin that sticks out.
Males always chase females around the aquarium most of the time. So the chaser is nearly always male, and the chase is female.
When boy goldfish want to mate, they get white spots on their tail. If your goldfish has a spotty tail, it's definitely a male. If it doesn't, it's a girl or a boy who's just not ready yet.
The male will develop white bumps on their gills and the females stomach area will enlarge as she fills with eggs. Also, the female will have a slightly larger and protruding vent. And they will also look lopsided.
rip it open and if the guts are purple its a girl LOL
A female goldfish grows at a slower rate then a male goldfish
wrong!!!!!!!!!!!!!!!
- A girl goldfish has a protruding anus, a male does not.
All goldfish are sexed the same way. During their breeding season the males develop white spots on their gill plates and pectoral fins. The females simply get a chubby tummy.

a boy has a thinner body a girl has a fatter bodya boy has little white spots on it's fin and a girl dosn't
Could be a boy or a girl ....
the girl is bigger
About at 7 to 8 weeks-DANIELLE LANDRY
the gold fish is a boy if both its sides are the same size, but if the fish is a girl one side will be bigger than the other (it looks pregnant on one side of its body) And also sometimes girls are pregnant.
Usually if your goldfish is a boy it will chase the girl around..also it will be more narrow if you look at it from the top and the girl will be fatter (due to pregnancy). Another way to tell is the fin. If the fin is more of a wave it is a girl; if the fin is more of a spike then your fish is a boy. Hope this helps!
