I have raised 4 koi for the last few years. They are currently about 12"
long.

About three weeks ago, I added three small koi to the pond. Everybody
seemed to be doing fine.



Did you quarantine them? Here in the UK there has been some mad virus
running around for the last year or so that kills Koi - you have to be
careful where you buy them at the moment.
