how can i tell the sex of my goldfish?

Answer 1

Goldfish are indistinguisable until they are "excited", then the male will develope small tuberocities over its body that look like little warts.

Answer 2

There are a few ways to sex goldfish. This is best done after the fish has reached sexual maturity, which may occur anywhere from 9 months to 2 years after hatching. This is easiest to accomplish during breeding, when males chase and nip at females. The males also develop breeding tubercles, which look like small white spots or pimples on their gill covers and this should not be confused with the parasite, Ich, which would also be on other areas of the body. It is possible for females to develop tubercles, but this is rare and they develop fewer than the males do. During breeding, the female goldfish's body may become larger, indicating that she is carrying eggs.

The most reliable method of determining your goldfish’s gender is by examining the fish's anal opening, which is located under its’ underside between the tail and anal fins. If the vent sticks out a bit, you have a female. A male’s vent does not stick out, but instead goes inward.

In general, females are usually larger in body and have larger anal fins than males. Males usually have thicker and longer pectoral fins than females.

Another sexing technique, which is not very reliable, looks at symmetry of the goldfish’s body. With this technique, when viewing the goldfish from the top down, the sides of the male’s body are more narrow and symmetrical, while the female's sides are more broad and asymmetric.

Answer 4

the male will have a pimple like white dots on his gills when he is ready to mate. females don't, except in very rare cases. females will also become very plump when full with eggs. the male will chase the female around until she starts spraying the eggs. they spray them everywhere, some even gets on the hood. beware!
for if you don't have one, it'll get on your curtains, carpet, whatever. and it sticks to whatever it touches first. if you let it dry.. well, don't let it dry.

Answer 5

Are you sure you really want to know?

umm well I don`t know how I could tell, so my best idea would be to take it to the vet or sumthing. Or you can just ask it. Just be like, ''[NAME], are you a boy or girl?''
