How long does it take for goldfishes to reach maturity?

Question

I'm not sure if it depends on the type of goldfishes, but the ones I'm trying to find out are the common goldfishes. I'm pretty sure it is the common goldfish.

Answer 1

As far as sexual maturity, they can reach this in 1 to 1 1/2 years. But it will take them much longer to reach their full length, if that's what you're asking. Goldfish do most of their growing in their first few year, but never actually stop - the growth rate just slows down.
