      Help! (Tank Koi)

      So I'm new and I don't have a pond.

      I have a Koi (Mr. Grouper as my kids call him) who mysteriously turned white and is now at the bottom of the tank on its side or upside-down. Fish is breathing, but is struggling. Tail looks stiff too.

      I have have not tried to add fish to the tank in over a year.

      The Koi has 1 tank mate, a Sun Catfish.

      Tank Side: 55g
      Filtration: Fluval FX6
      Temp: 73.5F
      Water: Tap w/ Seachem Prime as a conditioner

      I panicked when I got home from work and did a large water change (probably 60%) before doing any measurements.

      Koi is still on the bottom, but now this weird white "fuzz" is flaking off him -- best way to describe it -- and his color is coming back.

      I've attached pics. Does he have a chance to survive? Or is he suffering? Not sure what is up.

      Ok. So 30-45 mins post water change, Koi is trying to flip over and the white "fuzz" is flaking off really heavily and getting sucked into the filter.

      He's still getting stuck on his side or back, but is a million times more lively. Not sure what is happening.

      The catfish is fine, showing no similar issues.

      Do you have any test kits to test the pH or KH of your water, both in the tank and from your tap? This looks like a pH crash to me, where the pH suddenly starts dropping to a level which is toxic. Please post test results if you can, API is the most available brand and you want the drops, not the strips. (If you're picking up test kits, you should also get an ammonia and a nitrite test).

      In the mean time, continue to do a 50% water change daily and don't forget the Prime. And I would make plans for a larger container -- Koi get quite large and this tank will soon be too small for him to turn around in.

      Mary - Thank you for the feedback.

      7:10AM ET Update:

      My Koi is back to upright and is swimming some, but it's back-half looks off -- almost stiff. And his tail is turning red, as well as hit other fins and around his mouth.

      Will do a test. Shortly.

      Test Results as of 4:40pm ET

      Tank pH: 6.8
      Tank Nitrite: 0 ppm
      Tank Ammonia: .5ppm

      Did a 50% water change after measurements.

      Koi is upright, however not moving much. After the water changed, he swam around like normal for 30 seconds or so, then went back to resting on the bottom. He did take some big gulps of air and shot them out his gills.

      The Koi's fins are white with a dark red/maroon coloring to them now with ratted edges. The base of his fins and his mouth are red as well.

      Assuming Fin Rot. Ordered so API Melafix Bacterial Infection Remedy.

      Melafix smells good but does little else.
      The redness in the mouth and at the base of the fins sounds like a bacterial problem and I've
      only had success with Tricide-Neo with those type of issues, or injectable antibiotics.

      Once when I was fishing for sunfish and crappy (pan fish), I kept the fish alive buy keeping them in a 5 gallon bucket while I continue fishing. I notice after a while the oldest caught fish would lay on their sides; normal from experience. By accident I changed the water and I noticed all were almost immediately up and swimming around. I kept doing this to keep them alive, until of course, I have to clean them. So in your tank, maybe you are experiencing a classic sign of filter failure; as if there is no filter. You'll have to keep changing water for now as greybird advised to keep them alive post #3. Question - when was the last time you really cleaned your filter and the rocks at the bottom of that tank before this problem started?

      Inosko, I have found oxolinic acid baths to be very effective when battling bacterial infections. You can buy it online under the brand name Wipeout: https://www.thepondoutlet.com/wipeou...yABEgKotvD_BwE

      In a shady spot, set up a Rubbermaid tub that's longer than the koi, measure out 5 gallons of water into it and add water conditioner and an air stone. Measure out just under .5 gram (.473 gram, to be exact ��), mix it in, and put the fish in. Partially cover the tub so the fish can't jump out. Monitor for 30 minutes. If the fish tolerates it well, you can leave in for up to 2 hours. Repeat every other day for a week. Some people add it to the whole system, as in a quarantine tank, but it will kill your filter.

      It doesn't sound like your filter is working very well -- those could be ammonia burns. A larger environment and larger filter are in order, I'm afraid.

      Thanks for the feedback everyone. My Koi has done a 180 in the last 36 hours.

      My LFS expert sold me some APIŽ E.M. ERYTHROMYCIN and API MELAFIX. I yanked the Carbon from my FX6 and added the treatments to the tank.

      I'm going to be following the 4 day dosage cycle, hopefully healing up my friend.

      After that -- I need to find him a new home. I don't have a pond myself. There is a local pond with bluegill, carp, etc. But that would be inappropriate to dump him there.

      I'm going to search for a new home before the fall/winter hits here in Ohio.

      Thanks again.

      Lou

      Final Update:

      Mr. Grouper pulled through. Just finished the last dose of meds. He’s back to normal and the red on his fins and mouth have gone away.

      Thanks for much for the info.

      Now to find him a new home.

      Wow.....I just have to say......I do not think I have ever seen a fish that looked that bad ever pull-through. You have done well.
