When Can Koi & Goldfish Be Moved From an Aquarium Back to the Pond?


A customer recently emailed this question to Aquatic Connections. "My son bought some koi and shubunkins for our pond at christmas time and has kept them indoor in an aquarium. When and how do we adapt the fish to our pond. Our water temp is 52 degrees right now."

Aquatic Connections Response: Ideally, koi and goldfish only like a water temperature change of about 2-5 degrees. We aren't selling koi or goldfish at Aquatic Connections right now (March-Early April)because there is too much of a difference from our tanks to most people's ponds. I would wait longer. I would get your pond water tested and make sure the water quality is good right before you are ready to transfer the fish. You'll want to add pond salt and stress coat to the pond. What you'll do is put some aquarium water in a plastic bag and put the koi and shubunkins in that (or several bags). Tie the bags and float them in the pond for 15-20 minutes to let the fish get used to the temperature. Then you'll open the bags and use a net to scoop them out. You don't want to dump the aquarium water in the pond because it could change your water quality. Hope this helps. Let me know if you have any more questions.

If you have any tips, comments or suggestions on moving koi and goldfish from aquariums to an outdoor pond, please post your comment here.

The fish tanks at Aquatic Connections were exposed to the colder air temperatures beginning about a month ago as we opened up the sides of our fish house. The temperature in the tanks gradually dropped so the fish adjusted well. Since they are exposed to the cooler outside air and the water temperature has decreased, we are able to sell fish for people to put in their ponds.

We still think that a 10 degree difference is too drastic and would wait until the pond water warms up a little more.

Koi & Goldfish are living on Aquarium water. Its tempature are normal and he live on long life for this Aquarium. If you change to pond means tempature will be changed and affected on Koi & Goldfish.
