I walked out yesterday morning to feed my fish. I noticed one of my koi (orange w/white stripe) seemed unable to come up to the top and get food. He could swim around just fine albeit a bit slower than the others, but not much slower if at all. But then the oddest thing happened, he shook his head! Then he did it again, and again. I thought maybe there was something caught in his throat or something. Anyone ever seen this type of activity? He did eat some, but came to the surface slower than usual... I hope he is OK....
Thanks
