Carolyn,

First thing that I would do is test all water parameters, pH, ammonia and
nitrites being the most important. It the water parameters are out, then
all the treatments in the world will not help. Second thing that I would do
is change 10 to 25% of the water to give them some really good new water.
Then it is time to start worrying over treatments. Go to

I just went out to check on my fish for the first time in a while. The
goldfish seem to have white spots all over them, the fantails look like
they
have been through a paper shredder! I have one koi with a yellowish bump
on
it's side, almost looks crusty, with the scales sticking out. What can I
do
for them? Do I have to isolate them, or do I treat the whole pond?
TIA
Carolyn
