Will koi continue to grow?

[ZEROPILOT]

I recently blew out my two small, plaatic, formed ponds to make one free formed pond that made use of the two previous holes and more or less connected them.
My calculations have the new pond at just over 1,440 gallons.
I currently have two 4 inch Ranchu. 9 koi mostly in the 5 inch range, although one is 8 inches. And one comet. Also over 7 inches.
My question is will my koi grow to 3 feet long in such a smallish pond? Or will the pond dictate the overall size reached by the fishes.
Will I need to rehome koi at a later date?
Maybe dig an even deeper pond?

YEP .it is not true that fish only grow to the size of the home .I took 2 koi out last spring in a small pond and they were over 2 feet long and could not even move around .Not sure how they survived in about 1000 gallons with all the plants .Rehomed them to a new pond .

I have a lot of back yard space that could be dug up to house truly giant adults.
How long do I have to convince my wife?

I think genetics play a big role in how large a koi will grow.

The day you rent the backhoe, purchase a diamond ring at the same time and you'll find the wait will be over quite quickly...

It's unlikely your Koi will ever be 3 ft long as it is a lot of work to raise Koi to that size, and genetics and species type play a huge role in size as well. A 3ft Koi would be almost 30 lbs! See charts below: http://www.coloradokoi.com/koi_weight.htm
Re convincing your wife. I have been married almost 25 years. You will have to work together to find a happy medium. You may want to try to go on local pond tours or join a Koi club, etc so she has an equal appreciation of ponds and fish. My wife was absolutely not on board with a large expansion of my pond until we moved and built a new pond. Our compromise was she pretty much got to dictate the plans for the new home and I got to do what I wanted with the pond within reason. From when I wanted the larger pond until it happened took 8 years!

If you have the room, I would dig a pond as large and deep as you can afford, koi are addictive!

Three feet? Almost absolutely impossible ... Did, dig and dig! Even in my 2000 gallon pond, my koi range from 15" to 24" and that's since 2012. I had a Koi pond for 25 years but lost all but 2 during SS Sandy. 2 survived! It depends on many variables and pond size is one, feeding amount another, genetics play a part and water quality ....

I can just see it him on his knees begging his wife please ,please Bigger pond and this is the last thing I will ask for .My sons would do that with things they wanted .They really thought it worked each time and sad to say it did .

Just don't feed growth food! I use color - growth food and have had 1 year old koi at 16"! I have had 3 that have reached 36" including Big Mama who I had for 25 years. She weighed out at over 40lbs.

We got Donald and Hillary on January 21th this year..... They were large before the summer feeding, I placed a steel yardstick in the bottom of the pond and took pictures as they swam by, Donald is 30" body length not counting tail fin and Hillary is 28"..... They are both males, but what is amazing is the change in girth from a summer of good food and good water

You are SOOOO right.
It's exactly what I do if I want a new motorcycle.
