Yellow head on male koi

[l113892]

What is it about male koi that causes the yellow head and even yellow tint to the body? I think that bothers me more than the male conformation.

I have seen it on female Koi as well, but not very often.

I am pretty sure it is the DSB.....

As thought to newbies that they should stay away from koi with that type of tint to the shiroji be it male or female. A gambling man(experienced hobbyist) would probably buy this koi knowing his water and koi diet can clear it up some what. If the koi is cheap enough to test your skill, I would buy it.

Yeah Mike , You should buy that koi

It's interesting that you guys brought this up b/c I was just thinking the same thing about a male Hoshikin kohaku that a dealer in SoCal has posted on his website (I refrain from mentioning the dealer and posting a pix of the koi for fear of plagiarism). Considering the cost of the koi, I am pretty sure that the head will clear up. My question is, in male koi with yellow head, will all of them clear up with time/age, or is there a genetic/environmental factor to it as well?

Lam: No. Not even when quite expensive. If out of the mud for more than a couple of months, you should assume that a yellowed male is what he will become.
