Could be a boy or a girl ....
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!
