Fish aren't like cats (because majority of calico cats are female, hehe). But the only way to really tell is around breeding season. You need to look for breeding tubercules.

This site offers images of what to look for.

EDIT:

It only applies to cats. You can look at their vents (butts, a**s, whatever you wanna call it), but that is kinda hard to determine.  The females have bigger vents. It's relatively hard to breed goldfish from what I've heard. Pretty much the only way to tell is by the tubercules or if a female has a load of eggs
