How do goldfish breed?

You should see that the female goldfish appears fatter than usual due to the eggs she is carrying. The male will have white spots on his front fins and gill covers and will pay the female a lot of attention chasing her around the tank or pond. The female will lay her eggs on strands of pond weed which the male will fertilise with his milt. The eggs will hatch in 48 to 72 hours emerging as small fish known as fry.
They breed best in a pond. Feed them up well for a few weeks with earthworms etc and provide plenty of surface plants for them to spawn in. They will come into breeding mode as the temperature is raised up towards 70F and usually spawn at dawn.

Yes, in the summer months. If you have an aquarium with a heater, turn the heater down to colder temperatures (remember goldfish can live in freezing temperatures, surviving fierce winters in outdoor ponds, although I wouldn't recommend putting your goldfish through that if it's avoidable.) and after your aquarium water is cold for roughly a month begin to heat the water back up (do this gradually over 2 weeks or so as to not cause shock to them) and then when the water is hot they'll believe it's summer and it'll be egg-makin' time! Do some research on what kind of conditions a fry(baby goldfish) needs to survive. but that's the basics of it. Time of year is a factor! In late Spring to early summer is goldfish breeding season, this is primarily caused by the drop in water temperature, naturally caused by winter, and then the rise of temperature in Spring.

That depends on what you wish to do with the progeny. Keep or sell? The rarer more expensive fancy goldfish types could be sold for more $$$ but do you have the facilities and knowledge to be able to rear the several thousand fish you would get from one single spawning and do you also have the contacts required for marketing them?

When goldfish are breeding, the male usually will chase the female. This is pretty easy to witness, because the male will do this frequently. You may also see the male pushing the female into a soft plant, that means they are spawning.

P.S. To tell the gender of the goldfish, look for white spots (Breeding Stars) on the fish's fins or gills. That means its a male.

Yes. The problem is simply that most people can't keep goldfish alive until sexual maturity because they are usually kept in tanks too small for them and they die young.

A Fightn' Fact-

Fancy goldfish: 1 Fish= 29+ Gallons

1-Tail Goldfish: 1 Fish= 55+ Gallons

To increase the chances of your goldfish breeding, you will need to put them through a period of conditioning. This includes feeding them a diet rich in protein, doing plenty of water changes, and lowering the tanks temperature by about 10 degrees F. When your fish start chasing each other's rears and the females begin to look slightly fatter than usual you should raise the tanks temperature back to normal- this should trigger the fish to spawn.

No. Completely impossible. It would be the equivalent of a cow and a horse breeding!
