    A comet goldfish will grow approximately 6″ its first year of life. By the second year it will only grow another 2-3 inches then be fully grown by maturity at 3. that is to say they are housed properly. A comet rarely grows much more than 12″.

    A common would be the same and would take about 3 years to reach 12-14 inches. His/her growth rate will slow but he will keep growing.

    Mind you that genetics, food, housing and care (mostly genetics) will determine the overall growth rate.

    They do continue to grow their entire lives, though…just at a much reduced rate. I have a 12″+ comet in my care that is about 8 years old. Couldn’t tell you how long he’s been that large, though.
