Many fish are hermaphrodites -- which means that any one fish can make both
sperm and eggs -- but goldfish are either male or female, just like people.
Unfortunately, most of the time you can't tell the difference between the
two sexes. 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 females become fatter as they
fill with eggs to spawn, and the males develop tiny white spots on their
head and gill covers.

Answer 3

Your fish are coming up fin rot, in a 2.5 they are going to be turning the water poisonous interior of 12 hours, no longer even each and every 3 days is sufficient, it would choose to be each and daily water variations, that are very demanding for the fish, for this reason a 2.5 being a lose lose project for Goldfish! poor water high quality additionally will set off swimbladder issues, as will feeding them floating ingredients. this would additionally be the source of the nipping, Goldfish are bullies and crammed right into a 2.5 it would be such as you being shoved in a small cloth cabinet with yet somebody else, very demanding! If the biggest tank you may have is a 10g, return the Goldfish to the save and swap them for a unmarried Betta in a minimum of a 5-10g heated and cycled tank. Whoever "recommended" a 2.5 for a pair of Goldfish desires a slap upside the pinnacle, completely misinformed and incorrect! For a pair of Fancy Goldfish (of which Orandas must be finished grown at 2-3 years previous, a minimum of 6" in physique length different than for fins) you go with a minimum of a 30 gallon, with filtration for double the quantity of the tank. Goldfish at the instant are not low priced hassle-free pets!

Answer 4

You can't tell unless they are 'in season'.

And even then it can be hard!! I've had goldfish forever, when I was younger. Sometimes 6 to 15 at a time which each individually lived between five and ten years sometimes four inches long or bigger (these were not koi).

I only ever had one that I knew for sure was a male (had pearly like bumps on his operculum seasonally). I can't believe all the rest were females, but they never filled up with eggs and none of the others ever got the bumps on the operculum. I bred guppies and betta but never could pass GO with the goldfish. :)

Answer 5

Boy or Girl?

How can you tell whether your Goldfish is male or female? You might want to know because you want to breed them, or give them the right name before Jack turns out to be the mother Goldfish! 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! It's the natural tendency on part of the male goldfish to chase and nudge at a female's rear part.


hope this helps you in what your lookng for ..

Answer 6

Firstly, 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.
Physical sexual characters

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

Answer 7

I think's it's to do with the shape and size of the fins on the underside of the fish.

I used to have a book about tropical fish that said as much. Sorry, can't remember what the book was or what the difference was!

Bit of a pathetic answer - Sorry!

Answer 8

if they are 3 inches or larger you can tell by looking down at their backs, the male will be slender but the female will bulge more
especially on her right side (they only have one ovary & its one the right side)
in the springtime when they are ready to breed the male will get these white dots on his gill plates (tubercles) that indicates its time
