Hi BK

I have a goldfish (eight years now!) and he/she started out all gold
with some black on tail fin and after a few years, the fish started
losing the gold color. I had called the pet center the fish came from
and they assured me that goldfish will often change colors. The fish is
now all white, very large. My two shubunkins and comet (I have had these
fish over five years) have stayed same colors.
