No matter if you’re moving your Koi from one pond to another, or bringing your Koi fish home for the first time from the store, it’s important to slowly add the fish to your pond.
If you’re bringing your Koi fish home after purchasing, they’ll usually come in separate bags or containers of water. Place these bags with the fish in the pond and allow the water to adjust to the pond’s temperature. This will prevent any shock from sudden temperature change.
