how do you tell the sex of a goldfish ?

Question

They are comets, fan tails and shubunkins

Answer 1

It is extremely difficult to tell the difference between male and female goldfish when the fry are less than a year old; however the females are likely to be bigger than their counterparts of the same age.

Here are some clues that might help you sort out the Goldfish boys from the Goldfish girls:

* 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!(just like the common factor in our human world) It's the natural tendency on part of the male goldfish to chase and nudge at a female's rear part.

Answer 2

As you've six goldfish, then you really likely have both sexes. they do no longer conveniently breed in an aquarium setup as they are inspired via the replacing seasons, notwithstanding it may ensue. even as they are waiting to spawn the lads will produce little raised, white spots on the gill covers. those are observed as breeding tubercles. they are likely to seem after the wintry climate even as spring is coming so seem out for them!

Answer 3

This time of year its easy to tell. If the fish are over 2 years old the males will have "pimples" on their gill covers, cheeks and on the leading edge of their pectoral fins. These are breeding tubricles. Assume the others are females. Chasers are boys, chased are girls.
Any other method I don't beleive, like size, or color, or shape of the fins. Or my fish just break all the rules. I have a small thin female with long triangular fins, and big fat males with rounded fins. So its hard to go by those methods.

Answer 4

sexing goldfish is hard i have exactly the same fish usually the female fishes are more plump and rounded than the males there slimer

Answer 5

Sunday gave you the most reliable method. See this website for photos of the tubercules: http://www.bristol-aquarists.org.uk/goldfish/info/sexing-fs.htm

Answer 6

Sexing your fish can be tricky but is not that difficult once you know what to look for.

The vent (or the butt) for females will be convex
For the males it will concave

that is about as difficult as it gets.

Answer 7

Pretty much impossible unless you are an experienced breeder

Answer 8

if the fin on top of it is long and flowy it's a boy. if it's short, it's a girl

Answer 9

what a question. i used to ask my teacher a question like this but about the bird. answer to ur question: i don't know.

Answer 10

Show it an add for shoes on sale. If it goes nuts it's female.
