My Husband and I have a 28"-30" Tancho, he/she might be between 12-15 years old.
Back in her day she had won a ribbon or two.
Her / his once almost perfect
red circle is today almost completely gone. The circle disappearance gradualy
started to change, it seems in the last year, As we opened the pond up this year
there was probably half of the pattern left, as of today it's almost completely
I have been told by various people that it could be a water issue,
we have never had any issues with the water. Maybe it's the food, we always used
a very reputable brand, to that the guy / girl is just getting ....OLD!. We see
no other color issues with any of the other koi in the pond.
Your thoughts please...

Two main possibilities. The first (and least likely) is a condition
the Japanese call Hikkui. It is a genetic failing causing promising young fish
to decolorize. They are working hard to eradicate it, mostly by not breeding fish
with bloodlines where it exists. Your fish is too old for this.
As a matter
of fact, that's most likely the problem. With the exception of the Asagi --where
red develops late and tends to be durable -- in most koi varieties, especially
the most "refined" (read inbred) GoSanke (Kohaku, Sanke and Showa) red is often
unstable and fades or disappears as the fish ages. It is genetic, and it is nothing
you did. The red tancho is gone for good. This seems to happen to tanchos more
than any other pattern. Just naturally unstable, I guess.
