Pigment or Problem ?

[Tula]

One of my koi's nose has lightened, within the last week. I will try for better pictures, but does this look like a pigment change, or a problem? I was surprised many years ago, when another of my koi, changed from orange and black to white and black. I've had this one for about a decade.

from the picture I think it is normal, just keep a eye on it.

It looks like normal compared to what I've seen.

Thank you for responding. I am keeping a close eye on it, as I looked through my pictures and it's definitely a change. I know I should have a QT tank set up , if treatment is necessary, so am giving that some thought. I have a 110 gallon stock tank, thinking about a simple filter idea. Hoping it isn't necessary.

Thank you for responding. I sure hope so....it's a worry. Sushi ( him / her ) name, is acting normally etc, but I'm watching him with the careful gaze of a ....heron - LOL . I'm hoping it's nothing to worry about .

Update. No change, so thinking it's a pigment change. I'm relieved, but will still keep a close eye on him / her.
