Goldfish become sexually Mature by two years, although this depends on the usefulness and diversity of the diet and the conditions in which they are contained. It is very important role is played by the volume of the aquarium per goldfish need at least 40 liters, and the whole "glass house" should be at least 100 liters. In small volumes of fish develop poorly, become like "trapped" and unable to spawn.
In ideal conditions, there have been cases earlier puberty - a half years, while diet was full of proteins. Consequently, before this age, even the experienced owner will not be able to distinguish between male and female.
