Urgent Help Needed for Koi (swim bladder disease?) #1
I have a koi which has for the past week been resting near the top of the water. Today I have noticed it swimming on its side and sometimes upside down. It also appears to be slightly bloated.

From researching these symptoms on the internet it seems as though it has swim bladder disease as this can affect the fish's balance in the water.

Is it best to wait to see if it gets better or is there something I can treat it with?

Please give me your suggestions. Any help much appreciated.

Thanks.

Hi Simon, welcome to the site

Do you have a tank set up to quarantine your koi? Also can you describe its symptoms a bit, is the swelling like a bump in one place or is it general swelling of the whole body. Can you see any scales sticking out? Can you tell us a bit about your pond, how long it's been established, how many fish and what types and the dimensions?

Sorry for all the questions

Hello Fishy-Fishy,

I do not have a quarantine tank set up at the moment and am not sure what sort of container would be suitable.

The fish appears to have general swelling over all of the lower part of its body. There doesn't appear to be any scales sticking out.

The pond is 13ft x 5ft and 5ft deep and has been established for about 8 years. The fish affected is a golden Israeli koi, there is another one of this type as well as a white koi together with five goldfish. All of these fish (with the exception of the diseased one)seem to be swimming around quite happily.

I hope this helps. Please let me know if you need to know anything else.

Hi Simon, sounds like a nice set up you have there
Does your fish show any other abnormal appearence other than the swelling? Are the fins intact?
Swimbladder is usually caused by something, usually constipation or a bacterial infection so I am trying to establish if anything else is wrong with the fish
I'm guessing they haven't been eating over the winter?

Thanks!

The fish's fins are intact. There doesn't appear to be any abnormalities with the fish - I haven't examined it by catching it with a net though for closer analysis though.

The fish haven't been fed over the winter.

Sounds like it could be a bacterial infection then
Since you don't have a place to quarantine your fish I would recommend using pond melafix, the second product on this page- click here. It is a natural product so it won't harm your other fish. Hopefully that will help.

Re: Urgent Help Needed for Koi (swim bladder disease?) #9
Koi don't get swimbladder problem in the same way that fancy goldfish tends to do. So I would agree with F-F that it is most likely bacterial. Bacterias can be problematic around winter-spring time. However, I think it would be better if you treat the koi in isolation rather than the whole pond. Even a large plastic tub with a filter will serve as a HT in an emergency. How large is the fish, BTW. Melafix is useful for healing exterior wounds but it does little for internal bacterial infection.
I know enough to know that I don't know enough

Re: Urgent Help Needed for Koi (swim bladder disease?) #10
Do you know the temperature of the pond? Also when you say the other fish are swimming around fine, how much are swimming around as depending your weather i would still expect to fish to not be moving alot.

Also as captk says there no point treating a outside pond in the winter, itll be too cold for the treatment to work.

If it a swim bladder problem, which its unlikely but possible depending how well the fish were spawned and breed, its nearly impossible to cure due to how the swimbladder works.
