Does goldfish growth slow down once they reach a certain size or age.
Has any body seen any figures on this. I've seen Koi growth graphs on
the web, but nothing for goldfish/shubunkins/comets. I wondered if that
size was related to pond dimensions. I've read that shubunkins can reach
12inches and goldfish 18in, how long does it take them to get this big?

Hi Peter,

I've seen goldfish in big ponds be 12" - 14" but not much more. As far as
how long does it take them to grow that big, depends. Depends on water
changes/quality, size of pond, and type of food.

To give you an idea, I had some fantail fry that I gave out to another
ponder. She put several in a 55 gallon tank, fed them heavily, did constant
water changes and watched them like a hawk. I, otoh, put a few in a 20
gallon, fed them 1/day, did water change twice/month. In 6 months time mine
were the size of a ping pong ball, hers were the size of a softball! There
was a difference though in quality of the colors, hers the orange was quite
faded against the white, but mine were still bright. I have since seen
articles regarding growing fish too fast can affect the coloring outcome in
a negative way. ~ jan
