wow Greg, that is pretty extreme, but then it can get frustrating, as we all know, unfortunately. I am sorry to hear that. I assume you quarantined?
We had an up and down year.. Some good results at shows, but did have some in quarantine problems on new arrivals with flukes that were very resistant to treatment. If that is a sentence.

Not much growth due to having all our koi in the 2400 gallon q pond. Lost one former GC to who knows what. No parasites, just a failure to thrive since she was shown in her one show 3 years ago. Finally I put her down this summer.
The q pond turned out just like I envisioned, but the big pond completion is a long story. next year will be better
