Well, they have to be mature also, which is about a few years of age.
Goldfish do breed in the Summer.
Usually Goldfish breed spring and early summer
Spring
In late spring of early summer is the best time to breed goldfish.
yes, goldfish can mate, if you keep your goldfish in a pond... they usually mate in spring, and if you keep your goldfish in a tank, they may mate anytime... but they usually dont do this until they are 3 years old, when they mate, the male will get breeding tubercles which looks like pimples but not red, then they will do a chase, when the female get tired she will release her eggs and the male will fertilize them. of course, you can also try to find ways to make them breed though... anyways... as animals are... they can pretty much all breed including goldfish!
Yes, goldfish can breed in the home aquarium.
Yes they can cross breed.

Goldfish do not have a breeding season. They can breed whenever the water is warm enough. In an open pond, this would be in the Spring and Summer months. In an indoor aquarium this can be year-round. Thank you very much for your answer!!
No. A goldfish can only breed with other Carassiusspecies.
