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.

How do you know if a goldfish is a he or she and how do you know?
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!
