Many, many tosai of tategoi candidate are turning to white fish in breeders' highly heated ponds during winter....
Contrarily, to keep a group of nice patterned but slightly lower beni quality koi in lower temp (lower than 18C) and then feed only color food in order to strengthen the basis of beni/hi plates is a popular handling and feeding techniques....
CHIHCI, it is said (in Japan) that higher PH cause thinner hi plates and decrease luster but red color tends to finishing/complete relatively faster, while very low PH break hi plates away easily which was observed by laboratory tests.
I think temp play a lot..... as far as I know, 24-25 C is known as best temp among the good range of 20-26C or so. Interestingly, tosai are lively in higher temp even 30C+, while matured koi prefer to a slightly lower temp around 22-24C....
Junichi-san, what do you call the water plant in your original photo's. I think this is a great idea to include this plant during a spawn, for fry and protect the large koi.

Thank you Junichi, since I am not trying to push rapidly to jumbo I welcome the cooler temps to give the koi a chance to consolidate the beni.
I don't expect I will be pushing them past what they can handle genetically. Steady growth has been working for me.
I still have a lot to learn and figuring out the "speed limits" on beni is out of my league.

they are not kanoko they are going to be shiro muji, its a shame but it happens, a kanoko would be a stable dappled hi, thats not what yours have, the one that hasnt lost its beni looks good though...
i've kept koi in fish tanks and heated vats, and have never had a koi lose its colour, you need to make sure the water is clean (good filtration and water changes) also offer a good mix of high quality foods, and lots of air, sunlight and algae also make a big difference

Any updates in fish? Are they pushing 20 inches yet?
This is crown sanke from Nakata koi farm. The winner of the 1978 All Japan Grand Championship. My super favorite fish of the season!!
Just saw Junichisan today and had a great talk about how to improve fish in general. Great and wise man and a great educator. He lives very near me and I wish I could visit with him more often. I believe, from what I have heard, Junichi has not been asked to stop posting but rather to not critique fish. He saw my post here in which I asked for my Sanke to be critiqued, he did not reply, but we had a very interesting talk about that fish today. We were at Andrew's Koi in Anaheim, Ca. The ZNA club was having a fish auction. Both of us belong to that ZNA club.
