Koi Dying For No Reason

Hi I was wondering if you could help me. I have a large Koi pond and since x mas, the majority of my fish have died. I have no idea whats wrong with them. At first they seem to bloat and then they float vertically, head up in the water, then they die. I have other fish, and they are unaffected. Have you got any idea what might be wrong or causing this? Any advice would be great.

Thanks,
Liz

It seems like your Koi have succumbed to an internal infection. That would explain why they would blow up, float funny and then expire. The other fish in your pond might have a better immune system or they might be unaffected by the thing that afflicted your Koi. The infection could have been caused by feeding when it's too cold, bad water quality, a suppressed immune system, ect.

Contact a local veterinarian that specializes in fish health & disease or a local Koi club. They will be able to provide you with more information. You need to find out exactly what caused the problem, a veterinarian or a club member will be able to visit your pond and will tell you how to fix it.
