When baby goldfish hatch from their eggs, it will take approximately seven days for them to assume the shape of a goldfish. However, it may take an entire year before the colour of a mature goldfish is fully developed. In the meantime, they will exhibit a shade of metallic brown.

As fry, the growth of pet goldfish is accelerated. This is a form of adaptation as they try to keep themselves from becoming the next meal of adult goldfish or perhaps insects and other fish in the tank.

When a goldfish is highly bred, it is sometimes possible for it to become stripped of the ability to breed in the natural fashion. In this case an artificial breeding method can be employed but it is not without its risks.
