Heated and Grew KOIs
The ideal water temperature for KOI is around 25°C.
If this water temperature is maintained over a period of time, the extreme feeding we recommend will be possible.
The fleshiness from the shoulders to the back is a good indicator of whether they have achieved this or not.
During the summer, keepers concentrate on feeding them with the same sense of schedule as if they were being released into a mud pond.
During this time they are not disturbed in any way to bring out the wildness in their swimming and behaviour.
We can see a tangible and obvious difference during the autumn and winter harvest.
They have a broader body shape, as if they had been kept in a Japanese pond.

I've posted one here before and I was going to post a link to that, but I couldn't find it when I looked for it, so here's a new one.
In any case, it was a long time ago, but at the time of TOSAI in the spring, it was a 14 cm, participating KOI in Grow and Show, and the price was £50, which was not cheap for me at the time.
She eventually reached 63cm at 5 SAI and was going to increase SUMI to 70cm, but Dennis, the shop manager in Cheshire, bought it for £2,000 because he could sell it as a TATEGOI.

A very nice fish by the sounds of it. That I would certainly have in my pond all day long.
But in a self titled heating and growing thread, concentrating on size then a 60cm ish Koi, hasn't done anything particularly special at 5 years old has it? Anything heated and auto feed appropriately would do the same wouldn't it. Its certainly impressive, and I would be well chuffed with that particular example. But what makes you bang the Koi behavior rhetoric at everyone constantly. I'm curious as to what makes it better than a heated pond plus decent food?
I'm also confused as to why you say people neglect the summer feeding? I don't believe that anyone who wants to grow Koi does do that?
However, I'm unheated and relatively new to keeping Koi. I don't think all my 5 year olds would be circa that. I had a disastrous season year before last, when they first went in the big pond. And last year was the first time they've had a feeder on the pond.
I'm not really bothered about bowling and measuring normally. But I'm interested for comparison now. I'll have to whip them out in the spring and see how they're getting along.
Perhaps I'm optimistic?

A nice fish but as mentioned by Alburglar, not overly impressive at 63cm 5 years in. I have managed to grow a koi from 18cm to 65cm in the same period of time and this particular fish was the first one in the pond which has had multiple years of issues meaning hugely disrupted growth. In fact, I would say that there has only been maybe 1 year without any real issues and that was this year but I had a new filter to mature so couldn't feed as hard as I would have liked to.
I have grown pretty much every tosai to a 40cm+ nisai again with bad disrupted years of things like bacterial infections and what not so whilst a lovely fish, it is pretty crazy to constantly crush the UK koi scene when we are seeing the same results as what you are using as an example of these methods you push (which match what literally every koi hobbiest I know does in the UK by the way).
This is all on an unheated pond...

Thanks for the reply I would but I was going to put a window in aswell, but thinking it's going...
