I meant to say the black stuff. She was all white before. This started to happen a few weeks ago when the weather warmed up. I also have another white comet doing the same albeit red not black.

You are sure you mean nitrate and not nitrite ?
My bad. I have a tetra liquid kid. Might of got the names mixed up, but I took a sample to my local aquatic centre and he tested my water with an API kit. He said my water was healthy, My PH has always been stuck at around 8 to 8.5.
I'm doing the weekly water changes to try and bring it down gradually

I would not worry so long as it is just the one koi. He looks to be young and I expect he is just changing color. It is not uncommon for black to surface on a white fish.

Your wromg there what about the tancho sanke.
But in another repect your perfectly correct it shouldnt be happening to a koi that has been white since you bought it, to be brutally honest in 27 years I have never come across anything like this before.
I've seen wounds turn black then ulcerous but there are no wounds in evidence,it's as you say also on a commet.
Give me a day or so to ask one of our clubs members who is former head of the BKKS Health Standards Committe but as to whether hes seen it.
As you know in white koi the blood vessels are close to the surface the, it may very well be be a thing called black blood which is brought on by high Ammonia, Nitrite or so I've been led to believe.
However your reporting all the perameters as ok, I dont understand how it is doing the same to the commet. unless the blood vessels are again close to the surface
I hope to know more within a few days about this condition and get back to you

Dave, I am clearly clueless on this subject, but have to ask at what point "fish" can not change color? I only used the term "fish" as I have been watching koi, comets and shubunkins all change ... not every fish mind you, but several, and all fairly young (largest to change is about 12-14" now). I understand water quality and food can play a role here, but my knowledge on this topic is minimal at best.

Appreciate your time Dave. He/she is acting just like my other fish. Has a huge appetite and is very active. I don't know how to identify male/female fish, but he/she is being chased around by the other fish in my pond, particularly by the orfe. Can you tell by the pics if its male or female. ?

The colours of fish be they koi or goldfish are constantly changing all the time, and can be manipulated by differing foods so in a sence the colours are in continual flux but you must be willing to experiment to see what brings out the best.

Yes quite right but all koi with sumi under the white if its undeveloped show blueish under the white .
I think its down to black blood
