how can you tell if you have a female or male goldfish?

Answer 1

* The female Goldfish are slightly bigger than the males and look
even heavier in the abdomen when they are full of eggs.

* Male Goldfish develop white spots on their gills and pectoral
called "breeding tubercles" during spawning time.

* Males have midline ridges on their undersides beginning from
the back of their pelvic fins and ending at their vent opening.
This feature can be absent or smaller in females.

* Males have firm abdomen while in females; the area between the
pelvic fins and the anal fins is more pliable.

* Male Goldfish have longer and pointed pectorals as well as
stiff fin ray, while females have more rounded pectorals and
shorter, finer front fin rays.

* Male goldfish have smaller and more oval anal openings and the
anal fins are not as thick as that of the female goldfish who has
a larger and rounder anal opening with a slight protrude. The
anal fin is also thicker.

* The spawning time is the easiest time to distinguish the boys
from the girls. The female opening will look larger and more
swollen as the eggs begin to ripen. She would look big and
heavier. Since fish reproduce through external fertilization, you
can make out when a male is ready by the white breeding tubercles
and you can actually push out the milt through his ventral
opening by running a gentle finger along his sides.

* There is one more obvious, but kind of time taking way to make
out which one of your fish is male and female. Find out who is
chasing who - the chaser will be the male and the chased and
tired out one will be the female! It's the natural tendency on
part of the male goldfish to chase and nudge at a female's rear
part.

Answer 2

In the spring the males will get tubricles on their gill plates and the leading edge of their pectoral fins. Females will not. Tubricles look like pimples or ick but only on the places mentioned above. There is no other way to tell. Fish that are less than 3 years old may not be mature enough to have tubricles so you might have to wait. Of coarse if you see it spitting eggs from its behind that would be a good indication of a female. Some people will tell you females have shorter fins and males longer but I know that to be false. I've got a male with short fins and a female with very long fins. I wouldn't worry too much about it. You can't make babies, it takes a whole new level of fish keeping to be able to do that. If however males are chasing a female you need to separate her, the males could run her to death. Don't be tempted to see if the eggs will hatch, the parents will eat them long before any mature, and your female fish will probably not survive the ordeal.

Answer 3

Answer 4

From their tail. The male's tail is slightly bigger and more beautiful than the female's.
