Thanks, I had them for about 6 or 7 years. It was worse than I thought. Yesterday was raining so hard I could really deal with it other than pull the two dead koi out. Today I got out there and all the koi died (4 in total) a bullfrog and a goldfish. They would all eat from my hand so its pretty sad.
I'm a little mad at myself because I have this double walled paneling used in greenhouses that I normally put over the pond and it rarely even ices over. But this year I had flu or something that had me pretty sick and I didn't get to do my normal water change/ and cover. Also weather man didn't really mention that it would be freezing for 2 weeks straight when it happened or I would have called someone to help me get the cover on. My heater had died and the farm supply store only had one for a bucket but I put the heater in the bucket and the bucket in the pond and it appeared to keep a hole open around the buckets. Maybe it wasn't a big enough hole. A few days I heated an old fashioned pressure cooker up and melted a second hole in the ice. At that point I did see one of the koi near the top. Maybe I should have thought that unusual but I didn't think much about it. I thought they were just up for the sun. I tested the water today and it didn't test so bad considering the amount of dead fish in there. Some nitrates and some ammonia. But I have to assume its lack of oxygen because the readings weren't that bad. Times likes this you really question if its worth the trouble.
Oh man, I'm really sorry! I've never been able to get mine to hand feed, that must have been very special.
I don't think many of us expected such arctic weather for weeks on end
I'm sure you're sad, but don't beat yourself up, you were sick. We warmed up for several days, now it's very cold again and expected to stay that way this week.
To make matters worse, our 11 year old Trane heat pump died
We're running on auxiliary power and our new system will be installed Wed. and Th......during frigid weather !!
