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!
for only he goldfish or fish know that
He doesn't know how to.
I don't know except do not put goldfish in the same tank as anything else the other thing will die. I know from experience. :*(

Goldfish spawn in groups in springtime when the water temperature approaches 70F. They do not have live babies.

Female Fantail goldfish can not get pregnant they lay/scatter eggs when they are chased by males . So you have nothing to worry about.
