Golds are difficult to sex. Although it *is* possible. The best and most accurate way, in my opinion, is the tubercules that develop on the gill plates of the mature male. They appear to be tiny white spots, you probably won't even notice them without close examination of the fish. Females also are usually a big larger fuller bodied. It is nearly impossible to sex a Goldfish accurately under the age of 1.5 - 2 years of age, even then it is quite a task.


Another answer I found....
There are a few ways to sex goldfish. This is best done after the fish has reached sexual maturity, which may occur anywhere from 9 months to 2 years after hatching. This is easiest to accomplish during breeding, when males chase and nip at females. The males also develop “breeding tubercles”, which look like small white spots or pimples on their gill covers and this should not be confused with the parasite, Ich, which would also be on other areas of the body. It is possible for females to develop tubercles, but this is rare and they develop fewer than the males do. During breeding, the female goldfish's body may become larger, indicating that she is carrying eggs.

The most reliable method of determining your goldfish’s gender is by examining the fish's vent (anal opening), which is located under its’ underside between the tail and anal fins. If the vent sticks out a bit, you have a female. A male’s vent does not stick out, but instead goes inward.

In general, females are usually larger in body and have larger anal fins than males. Males usually have thicker and longer pectoral fins than females.

Another sexing technique, which is not very reliable, looks at symmetry of the goldfish’s body. With this technique, when viewing the goldfish from the top down, the sides of the male’s body are more narrow and symmetrical, while the female's sides are more broad and asymmetric



Tips on spawning...
At all times the water temperature which the fish are being transferred into should be at least 65 degrees Fahrenheit (18 degrees Centigrade). The ideal time to introduce your fish into the breeding tank is in the early evening and then the temperature should be raised gradually until it reaches 70 degrees Fahrenheit (20 degrees Centigrade). Sometimes the fish may start chasing during the first night and spawn the next day, but more often than not spawning takes place a few days later. Fish can be stimulated by putting in fresh water from a hose pipe under pressure; this is best carried out at night-time.

The fish will start to spawn early in the morning, and will generally carry on until midday. Do not be in a hurry to separate them if they stop chasing because they will periodically stop for a rest and then start again. Care must be taken to guard against any fish that eat the eggs - these must be removed as soon as possible.

noramly male has white spots on gills female dont
there is no breeding time in tank fish but to increese breeding you can rase temp slightly by a degree or so and this increases
the chance of babys
but the adult will eat the eggs so realy you need a breeding tank!

well, usually (atleast in angel fish) the girl is more territorial because she's holding the babys. I don't know about the breeding, when my fish layed eggs, nothing realy changed accept the girl got even more territorial.

No 1: You don't get chinese goldfish
No 2: You probably won't get em to breed, it takes years of practice sort of like doing it yourself really

all i can say is when our fish bred it was outside in the pond it was warm and after a thunder storm both times and we dont know which was which and they laid the eggs in the plants and the male ( i assume) kept chasing the other one round the pond and they stayed in the plants together
