Hi, I am sorry for your loss. I had a mass tadpole death last year but
it was my fault. This year, so far, so good. It really sounds like
poisoning to me. Good luck in the future....

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
