Go to
http://www.koitulsa.org/pages/800287/index.htm and see if any of their
members are koi health advisors or if they have any trained health hotline
people that can do a microscopic evaluation. I suspect that it is
parasites, but I like to taylor the treatment to the particular parasite,
not the shotgun approach. Some of the treatments can be harmful/stressful
to the fish, and not affect the parasites, while some other treatment will
take care of the parasite with minimum damage to the fish.

Hi Ray,
that's too bad :-(
A few questions before the experts arrive, -
How many fish in the pond and appx. how big are they?
Water test results, exact numbers?
malachite green This can be fatal to amphibians. Did they die before
or
after you treated?
Hope someone has an answer for you.

I am in need of some advice and hope you could help.
I am having a fish die-off. They are goldfish and the pond is about 6
years
old. I have never had anything like this happen before. There aren't any
appearant signs of infection on the fish. The only symptoms that I see
are
listlessness at the end of their life. They lose their appetite.
There haven't been any plant or fish additions to the pond. The only
connection that I have seen is this-toads come to mate in my pond as in
previous years. This year, I found a dead toad floating in my pond, which
I
took out. That was about 3-4 weeks ago. Later, all of the tadpoles died
off. There currently are more and they seem to be doing all right. In
the
past week, I have had 1-3 fish die every day. Is it possible that the
toad
carried a virus that infected the fish?
I have done a water change this past weekend of about 30%. I medicated it
twice with a combination of formalin and malachite green. The pond is
about
3,000 gallons and has an external filtering system.
I am at a loss. None of the diseases that I have seen described match
this.
I am hoping someone will have some suggestions.
Thanks,
Ray
kathy :-)
