How do I tell a female goldfish from a male goldfish?

Question

Any physical trait differences?

Also I've heard rumors of asexual fish. Is it true that a fish can be.

I don't want to breed them I just want to be able to tell the difference!!!!

Answer 1

Wow, there are some really bad answers to this question, a couple good ones. Basically the folks who are telling you it's tough are right. the best way is to look for the slimer fish, males and the bumps on the gill covers, also males.

Answer 2

First, sexing young and juvenile goldfish is virtually impossible, you have to wait until the fish reach breeding age (usually one year old). Secondly, sexing adult goldfish out of the breeding season is difficult, because the sexually distinguishing features only develop during the breeding season (in the spring time). That said, females may be deeper in the body than males. During the breeding season, the following physical features develop: males develop breeding tubercles (white pimples) on the gill covers and on the leading edge of the pectoral fins females develop a deeper body as they fill with roe (eggs), and have a larger vent (just before the anal fin) than the males.
Asexual means that one creature reproduces by itself. This is extremely rare in multicellular organism. Fish are not asexual. Some species alternate between the sexual and asexual strategies, known as heterogamy, depending on conditions. For example, the freshwater crustacean daphnia reproduces asexually in the spring to rapidly populate ponds, then switches to sexual reproduction as the intensity of competition and predation increases. Some young, lesser forms of animals may take a while to finally develop into their sex, but they aren't asexual.

Answer 3

once they are a year or two old you can look at thier vent and compare, males vents are flush with thier body and females are sclightly concave.
also in the spring males grow little whitw bumps on thier gill covers
good luck
also from my own experiences females tend to be a little more chary and males are a little more playful

Answer 4

It's very difficult.
Even trained professionals have trouble.
Breeding isn't the easiest thing to do either.
www.kokosgoldfish.com is a great resourse. Lots of breeding info.
good luck

Answer 5

you will definnitly see a slight buldge in the females body just forward of her vent, the males have a slimmer body

Answer 6

you really cant know the difference so probaly ask the person who sold them from you
