Hi all:
I've got 6 5-6" goldfish. One of them when he was a little one had some
black areas on him. I don't think it was a disease; I think he was kind of a
pinto goldfish.

Well, maybe it was a disease as now he's gold and white (about 50/50). He
has been getting whiter and whiter for the last 6 months and he has not
acted any different than the rest of them. There is no way I can catch him
and as he's in a 750 gallon pond with lots of hiding places.

I wouldn't be concerned but one of his buddies now has a little (1/4")
circle of white on his nose too. Have I been naive about this, should I be
concerned and if so, anybody have any suggestions?

Thanks,
BK
