One of the lfs has a ?full grown? black oranda. He is really gorgeous AND expensive. But he has tufts of white, almost like little fuzz or lint, in spots on his wen. This does not completely cover his wen just here and there. He's been there over a month and has always had these.
I know it's hard to diagnose something unseen and obviously I can't give you a picture or the water params. But this lfs is usually pretty good about quarantining if they have a problem. And I'm sure it's the price that has not sold him.
So I was wondering if this is what the breeding stars look like on the bigger goldfish or could this be something else?
