Koi Pond in the Winter

  • I have a Koi pond and it gets really cold in the winter. The top of the pond will freeze up. I feel bad for the fish but they seem to survive. Is there anything I should be doing or is near freezing water temps okay?

  • As long as there is a pond that is deep enough to where only to top layer of the water turns to ice (vs the whole actual pond water), and that the koi are over 1-2 years old, there should not be an issue with leaving them inside of the water.

    However, if any of those conditions are not met, then I would highly recommend placing them inside for the winter months until the ice starts to melt. Don't worry about feeding as their metabolism will slow down to barely anything when the water gets cold, and then will go back to normal once it hits spring/summer again.
