    What causes red fins and body on koi?

    Three weeks ago my large Goshiki developed redness in his tail fin and pecs. Also redness in his head and body, although not as acute. I can tell the red spotting on his head comes from within. I was suspecting some type of blood issue?. I'm scratching my head. I've tested all parameters and seem to be in line.

    if your water quality is in check,,,,that leaves parasitic,bacterial or viral........scrape and scope, plus a fecal float .....................visual inpection of the gills........check for color......................any other fish showing any signs????before answering that ,do a long visual check....shut all the running water ,,so you can get a good look

    two other fish are showing slight redness in their fins, occasional flashing.......

    I've been doing some reading and I keep coming with "Bacterial Hemorrhagic Septicemia" described as "blood decease"....

    Bacterial Hemorrhagic Septicemia symptoms include red streaks on the fins and body or redness in the body itself. For treatment you should use an antibiotic Koi disease medicine or oxytetracycline in feed or a fungicide/protozoacide dip/bath treatment in the water.

    I treated with 3cc of Baytril........ most literature talks a bout Tretacycling. I wonder if its the same?



    Another posibility could be Heteropolaria a protozoan infection, although it presents white cottony leisures at time confused with fungus that are not present in my situation.......

    oxytet isn't the same as baytril.......baytril is better........injection is preferable.......bacterial infenctions are secondary infections,,,,what the primary reason is,,needs to be addressed................parastites like tric,chil,and costia even flukes all can cause red streaking........my guess if it was a parasites ,it would be costia or tric............treatment of choice would be quick cure[proformC] or straight formalin..............

    a gill scrape,,,,plus around the gills,,,along the dorsal and tail fin....under the belly ...........how do the fishes eyes look ,,,,typical heavy infestestations of costia and tric ,can give the eyes a flatened look....almost like they are being sucked in[sunken like]...........many people panic thinking they have khv infection ,when they see the sunken eyes,,,,,,but in most cases ,it turn of to be costia or tric infestations.........tric can be seen at 100x mag...costia you need between 400-600x mag..............tric looks like wagon wheels spining around...........costia looks like coma's ,corkscrewing around

    the eyes actually appear to be a little swollen but most likely normal..... The koi loose apetite from a parasite infection? and How infectious is it? The one fish has been showing these syptoms for almost three week, since the Orlando Show.

    believe it or not, try fresh oranges. slice them thick and toss into the pond. I have a kohaku that does the same thing on body once in a while, red streaks. I try many things for her, salt baths, formalin, ect and nothing seem to work. added some oranges to pond and notice she became bright white and red went away. Most koi foods do not have enough vitamins in them, they cook them away with heat. Try some fresh c to their diet, can be grapefruit also.

    No its a big 4 yrs old Shusui that began showing syptoms after the Orlando show. I've never used proform c but last year the whole pond was treated with MG and Formalin + Supaberm

    On the vitamin C issue, if your Koi are not used to orange/citrus slices/quarters than you can soak their pellet food in fresh orange juice for about 5 minutes before feeding.

    I had/have the same problem with 3 of my fish; started this winter. Fish acted normal and all parameters are in acceptable range except ph is on the high side of acceptable (0 am, 0 nitrite, 7 nitrate, ph9).

    Lots of o2 and about 900 gallons per fish. I thought everything was perfect. I s/s 3 different times with nothing. I even quarantined them 8 weeks and treated them with proform c and prazi . . . no change. Then minn finn . . . no change. Then salt to .6% with tricide-neo dips(worried about impending bacterial infection) . . . no change. Scraped and scoped again. Still no problem. So i put them back in the big pond before i treated them to death. They still have light pink spider veins but no other symptoms.

    This is going on 3 months. I will see what Spring brings.

    I interject just to say your not alone and stay diligent ; you will win the war with the help of this community.

    Well I pulled the Shusui and placed in QT two days ago. I've treated twice with Baytril 3cc. Scraped three locations and found one to be suspect with what appears to be Costia (football size0 hundreds of them......not sure someone suggested it could be fish cells. They were moving but I thought it was water movement in the slide sample.... I'm not very comfortable with identifying stuff yet.....

    Bacterial infections is beginning to set in as sores are breaking skin. I should have isolated the fish much sooner but the QT hotel was full of new commers...... Moral is as soon as you suspect of something pull the fish and evaluate. From the surface you may miss something....

    Anyway I started a Malachite Green and Formalin treatment for three days, salt to .3/.4 in three days then 2 days of Supaverm. That should take care of all parasites.................... I've done it before and worked well for me.

    Wow your fish should be clean by now. Maybe you should have treated the whole pond rather than the fish in QT.

    I was suspect of my mains water, since I use well water, introducing any type of soluble irritant. But as I previously mentioned I believe there is a parasite problem that's in turn creating a bacterial complication. I'm just zapping the whole dam pond and QT.........
