* 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! Its the natural tendency on part of the male goldfish to chase and nudge at a females rear part.

Answer 3

It is a difficult task at best but there are a few ways to help determine the sex of your fish. It is a most difficult task on fry less than a year old, but as a general rule, females are likely to be bigger than the males of the same age. When they reach spawning age, and the eggs begin to mature in the female fish, she will thicken in the ventral area. At the same time, the male will start to develop small white tubercles on his gill plates and on the leading rays of his fins, particularly on the first ray of the pectoral fin which can usually be detected on fish with head growth.

Answer 4

Males have longer and pointed pectoral fins. Females have rounded and shorter front fin rays. Femal gold fish have slightly bigger heavier abdomens...especially when full of eggs. Males will develop white spots on the gills and pectoral fins when ready to spawn.

Answer 5

!!!congratulations!!!
you cant really tell the gender of a gold fish but in tropical fish the boys have larger brighter fins.

*well ya*

Answer 6

look at it's anal fin. when it swims or just stays still, if it stays like a rod against its body, it's a boy. if it fans out all the time, its a girl. but don't worry if you can't tell. it's not wierd. i just heard this from a friend and i dont' know if it's true but it seems like it.

Answer 7

not sure how true this is...but apparently if the fin on the underside is pointing backwards then its a male...the females is supposed to point down!The owner of an aquarium once told me!

Answer 8

By it's name. If you give it a boy name, it is a boy. If you give it a girl name, it is a girl.

Answer 9

The boys have bigger fins.

Answer 10

Fish are known to be able to change their gender. I wouldn't worry if I were you.
