Question
I have a koi pond for several years in Montana.  We have it heated in the winter.  One of the fish is floating on it's side, I brought it in and the more shallow water seemed to help I have given him ick meds. and  after 3 days inside is starting to float side ways again I have checked the water & it is fine.  What can I do for him??

Answer
Hello Sherri
I am not sure.
Sometimes this happens when Koi get really cold and the fat they have stored for the winter actually congeals inside their body.
But yours did it inside, also, and that puzzles me.
I would recommend consulting koivet.com
