Discovering how to breed goldfish can be a fun, easy and fascinating study into goldfish mating and spawning processes. If you have a breeding tank and five fertile goldfish, you are already on your way to many tiny fry. Breeding goldfish is far and away the most interesting part of keeping goldfish for me. It can also be the most frustrating part.

Goldfish breeding originated in China at the height of the Ming dynasty in approximately 1400 AD. This first elite and valued breeding stock was originally a political yet gracious gift from Japanese rulers to the Chinese rulers of the Ming Dynasty as a symbol of good will. Goldfish breeding is the answer why. As people get more into their hobby they would eventually like to see their fish breed. Goldfish breeding tends to be a rough and tumble affair.

Eggs should be incubated for 8 or 9 days at 18?C. Ten drops of 1% Methylene Blue should be added to each 10 litres of well-aerated aquarium water. Eggs will generally hatch in from 4 - 7 days, depending on the water temperature. The fry are quite small at the time of hatching, and feed for the first 3 -5 days on the attached yolk sac.

Spawning is stimulated with frequent water changes. Spawning mops or plants need to be in the water for the eggs to adhere to.

Learning how to breed goldfish is a rewarding part of fish-keeping.
