How can I tell the gender of my goldfish?

Answer 1

Here are someways to tell if your goldfish is male or female..
* 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

Many fish are hermaphrodites- - which means that any fish can make both sperm and eggs- - but goldfish are either male or female,just like people.Unfortunately, most of the time you cant tell the difference between the two sexes. the The only time you can tell whether a goldfish is male or female is during their breeding season. This is usually in the spring, since goldfish breeding behavior is triggered when the water they live in gets warmer.When goldfish get ready to breed,the female become fatter as they fill with eggs to spawn, and the develop tiny white spots on their head and gill covers. So yah thats how you could find out.

Answer 3

the male whilst spawning gets white tubercules on his gills that are white little zits. whilst the two goldfishes breed the male will chase the female goldfish after which in a month or so the female gets a great tummy. however to make certain the gender the golfishes they must be mature sufficient it relatively is whilst theyre spwaning and breeding.

Answer 4

Any body can tell me...
My male goldfish not develop tubercles its means he is not ready to mate.
But why my female goldfish swellon on her head like males?
I noticed this changes tomorrow it means my female fish ready to mate?
And you can check my profile there is my goldfishes video. Who can tell me after watching video how many male and female?

Answer 5

Put a picture of Reese Witherspoon or Denise Richards on the side of the bowl, and if the fish stay near that side, IT's a boy.
