I have a comet goldfish that is around 2 years old. It was in a 15 gallon for 3 months and then was moved to a 29 gallon. It is only 4 maybe 5 inches long. It seems very healthy...it eats a lot, swims a lot but seems to have stopped growing in the past year. I read online that they grow to be 12-14 inches. Is it possible that some comets may not be able to grow that large? This week I moved it to a 220 gallon tank. Will this allow it to grow larger? How long will it take for it to reach maybe 10"?
Can all goldfish reach max size?

They typically do the bulk of their growth in the first year or two, so it may impact the over all adult size of the fish, but he/she is likely still going to grow, just at a very slow rate now.
Chances are he/she will not reach the 'typical' comet size, but will be somewhat smaller.

Fancy goldfish only requires 30g, adult comets and common goldfish needs minimum of 75g... Yes they reach 12-14 inches, but also it depends on its genetics...

Goldfish growth depends upon many factors - genetics, water quality, water temperature, type of food, nitrate level, tank size, etc.
