How long can you stay underwater in a pond Koi Fish without air?
I have a small pond in my backyard with fish KB interior. I went to work this morning and when I returned (~ 12 hours later) was a layer of ice on the pond. I was able to digging holes in the ice, but how much long you can stay under water without air Koi Fish before he died?
I'm not sure how long you can stay under water but I'm sure its length. In winter, hibernate in the pond bottom and did not come until the ice melts!
