I just walked out to the pond today. Here seems like we have been a month behind, we had short sleeve temps on and off, for a few days, then cold, then sunny and warm! It was at the warm days in late Nov and now Dec, when the ice melted, I saw the koi ( I purchased more of them last early fall),comming up to the surface, I think they were looking for me, AND THEIR FOOD! Yes, they do learn to beg!! I know to stop feeding them early, before the temps get way down! They were down in the deeper part for quite some time! I think they are getting confused with the temps shooting up and down. Hopefully winter is here to stay, I JUST HATE SAYING THOSE WORDS

I went back to my notes from last winter, I read the pond was freezing over, then melting, then back to freeze. There were also several layers of ice, then 7-8 inches of heavy snow! Yes, the bullheads are catfish, they have those long barbs all along their mouths, and they are very, very, SHARP! I am going to try a net next summer, to try and get as many of those darn things as I can! I talked to a fella awhile back, and he said he would take all of the bullheads I can catch!! Thats all he wants in his pond! I am so happy just knowing that I can give them to someone who actually wants them, LOL
My koi that died were in the center of the pond, in the ice

I too was under the impression that 18 ft. of water was perfectly fine for all the fish, I WAS WRONG :'( I was given some fish this summer too The man was taking out his pond, so just offered them to me. I know one was a koi, but the rest are some kind of orange/red fish. I have yet to identify them. They do not look like koi, also with the disaster of the pond last winter, this spring I found 3-4 batches of that color fish at the deep end of the pond! They did not see me sneak up either! They looked so cute all gathered up like that

I am not sure where they came from? I thought all the koi remaining were males! Looking at the contour of their heads and abdomen.
