Are Koi Strong?

  • We are currently upgrading MFK. thanks! -neo
Koi are very hardy. I had one jump out of a pond and spent about an hour baking on the patio. I peeled her off the flagstone (leaving all her scales behind) and put her back in the pond, rubbed her gills till I could pry them open and spent half an hour pumping her gills and moving her around. That was 4 years ago. She is still doing fine and easy to spot due to the scale damage. I have seen ponds pea green with all the koi happy and eating. They actually prefer slightly murky ponds with mud bottoms. I used to house goldfish and koi together until the goldfish got some fungus and every one of them died (30) and not one of the koi got sick.
