      Fish issue

      Hi all I noticed yesterday that one of my fish was hanging on the bottom of the pond motionless. Not his usual behavior.

      Below is a film of him during feeding where I did get him to come up but you can see discoloration around his head. Any ideas? This morning I woke up and he was motionless on the floor the pond again. Thanks

      This koi is obviously in a bad shape.

      What I have learnt is that you should do the following to find out the cause:

      1) Measure water values: Normally NH3, NO2-, NO3-, KH, unless you have other unusual issues like well water can have.

      If the water values are OK, then:

      2) Do scrapings: at the lesion area of any, at the bottom of pectoral fins, some random places on the body, and the gills.

      Water quality probably not an issue. Other fish are behaving completely normal and look great. Recent frequent water changes and filtration cleaning. But I Will need to wait until tomorrow for additional water quality test kits. In the meantime Iím doing a massive water change. I only have PP on hand. No salt. Any additional recommendations? Never scraped before.

      I c. The water quality is probably good when the other koi are not affected. Then I would say that you cannot avoid doing scraping as it is probably a parasite problem. This summer I kept 6 small koi in the same water, one had severe lesions, 2 some redness but still looked healthy and happy, and 3 completely healthy. Scrapings showed that the first one had massive amount of fluke on its body.

      As the water quality is probably good then I doubt that you should do major water changes. A large water change can be stressful for the fish. Better continuous small changes.

      I'd get the water parameter test kits (ammonia, nitrite, nitrate, pH, KH, and temp) and get those numbers
      before doing anything else. Some fish are like canaries in a coal mine and will be effected by something
      long before any others. Sometimes not, but always a good place to start.

      Just did another water change and .3% salt for now as a precaution and he started moving around and looks better.

      Will get all the water testing stuff tomorrow AM

      Just tested everything ammonia nitrate nitrate all normal. Other fish still acting good. I did do a recent filter cleaning (3 days ago) that I let wait for too long. Perhaps this is a hangover from that period? Pond is very over filtered with bottom drain / sieve / lots of bio.

      Iím very hesitant to attempt scrape as I would need to buy equipment.

      Any other thoughts? He seems to be moving a little better with salt. Iím wondering if itís an injury?

      Considering a good PP treatment after this in preparing for cold weather.

      You will sooner or later find out that doing scraping and microscoping is a inevitable part of koi-keeping.

      Ok. Iím convinced. This was my first fish and I donít want to lose him.

      I read the stickyís and have clove oil but have been told to be ready with antibiotic too. Iíll talk to my dogís vet today but any suggestions on other supplies than microscope?

      Man, Iím really hoping this is not dropsy. His eyes and mid section are starting to bulge a bit. If itís incurable, do I put him out of his misery?
