    At about two years for males, and three years for females, goldfish begin to show signs that can help identify males and females. My darlings started to show and I was able to get a few good shots, so I thought I'd post them.

    Males develop tubercles, white spots on gill covers, as Napoleon, a comet, shows here:

    And as my little fancy shows here:

    However, Upstart, a female, has compeletely smooth gill covers:

    An excellent site with more photos can be found here:

    If anyone else has photos of their goldfish mating or showing tubercles, feel free to add them.

    between two and four years, depending on conditions. most show signs at two and a half, but can't actually breed until about three.

    Yeah, thanx. I think now one of my Shubs is male. But my two Wakins and the "Halloween" Shub are blank.

    How do you know how old your goldfish are? I have 6 goldfish and I have no idea how old they are.
