The girl tends to be bigger than the boy.
It's not easy to tell them apart.
The males don't get into fights and the females don't have marks, different colors like a lot of other animals, so it is hard to do it.
Also at some time of the year the female goldfish will get a bit fatter because she is full of goldfish eggs. With experience by observing them is possible to learn how to tell male and female goldfish apart by the thickness of their fins, the shape of their pectoral fins and the straight/thickness/firmness of their abdomens.
This happens to be a frequently asked question and I would be happy to answer it. You can only tell if a goldfish is a male during their mating season which their gill flaps/fin edges will have white specks and in the other hand female will become swollen with eggs.
Hope this helped! :)
The female has more of a V in her tail and mails donot.
They are only sexable during the breeding season (Spring) when the male develops white spots on his gill plates and sometimes on his pectoral fins and the female develops a chubby tummy.
There is no way to tell.

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!
