Some basic requirements include, plenty of space in the tank, the goldfish should be well fed with a balanced diet and the water should be in the ideal condition.
Before beginning your goldfish breeding journey, you must first make sure your main tank is well set with a filtration system, plants, especially live plants such as hornwort, a heater and a spawning mop.
A spawning mop is not only recommended because it helps to protect the eggs from their parents, but also, it makes it easy to move the fry into a separate tank once they are hatched.
Apart from setting up the main tank. You also need to set up a different tank where the fry will be kept once they are hatched. In the wild, goldfish breed in the warm season, spring. Therefore, breeding for goldfish is triggered by a change in temperature, from the cold winter season to the warmer spring. To replicate that in captivity, you need to adjust temperatures accordingly.
First set the tank into cold temperatures of about 10 to 12 degrees Celsius. Then when you want to trigger the goldfish into breeding, raise the temperature of the water from cold to ranges of about 20 to 23 degrees Celsius.
It is not very easy to tell the difference between a male and a female goldfish, because there are no necessarily visible external organs. For you to tell the gender of the goldfish, you have to wait until they are sexually mature or during the breeding age. Goldfish get to sexual maturity when they are about one-year-old.
To tell if your goldfish is male or female, below are a few pointers:. Looking at the fish from above, female goldfish appear to be usually shorter and rounder in their abdomen area. When they get near the breeding season, they become very plump, swelling with eggs on either one side of the belly or both sides.
However, it is important to note that a swollen belly can also be a sign of bacterial infection. Male goldfish on the other hand appear thinner and longer in their abdomen compared to their female counterparts.
The vent is located under the anal fin. For female goldfish, their vent can be seen from the side. When the female gets closer to the spawning season, their vent appears to be a small protrusion that is whitish in colour. If this happens, the breeding process was successful. Feed the new fish powdered fry food or brine shrimp for best survival rates.
Preparation for the fry is important for their survival. They need a separate tank, filtration and correct food. Once this is in place you can enjoy this fascinating lifecycle process of breeding goldfish.

To increase survival rates set up a separate breeding tank with filtration. Male goldfish characteristics. Goldfish fry can be seen throughout the summer and even into the early fall if the weather has been particularly hot during that time.
Sometimes a spawn can go on for a week or more and can put a great deal of stress on the female fish. The goldfish spend several days or even a week or more engaging in the chase before the actual spawn occurs. The fish spend hours each morning racing around the pond or aquarium, knocking each other around recklessly and dislodging plants, splashing water and basically acting crazy.
The chase is performed before the heat of the day gets too intense, around 1 to 2 p. After that time each day, the fish return to normal behavior. Sometimes if the water temperature stays warm long enough, the fish will spawn more than once. In warmer climates outdoor goldfish might spawn two or three times a season.
