    what could this be?

    Got home from work today and the tail of one of my koi is a terrible state looks like blood in the tail .water tests came out good and did a scrape on this koi and another koi and came up blank.
    Going to Do another on a different koi as I feel I must have missed something.
    But from the picture can anyone take a guess at what they think it is and how to find out if it is what you think.
    The koi is swimming fine and eating.

    Ok I've down another 3 scrapes as some of the other koi are flicking and come up blank, what magnification should I be using to see some of the smallest parasites.
    It's got to be parasites I'm just not seeing them.

    What would you recommend I do?

    Could it be caused by parasites as other koi have started to flash?

    10,000 dollar question, Jon pootkoi had similar looking fins, give his posts a look, you never know.

    Have you had a thunderstorm?? Or very heavy rain, this is happening across the country and the heavy rain could cause stress or ph changes. Also thunderstorms are high pressure and so the pressure could agitate the koi and cause stress?? If not then im not sure???

    Funny you should that my wife was just saying the same thing , we haven't as yet but are expecting them and the wife was saying maybe they know. I hope it is just that but I don't think so, I'm not that lucky.

    My fish are flicking and it's really annoying me, i scraped one which keeps sticking its head out the water and then going to the bottom to release the air, I think its clearing its gills from something but nothing came up on the slide. They all seem perfect and really happy at one moment and then no so happy the other. I don't know weather it's the blanket weed treatment in doing at the moment, but the flipping weed is not disappearing arghgh.

    Same here one minute they all seem fine then the next they do enough flicking for me to scrape which has come up blank each time. This has been going on for the last few days then I come home today after them looking fine yesterday and this ones tail is in a bad way and the others flicking. I have taken 4 scrapes today on different fish and blank.

    can you do a ph test every few hours and see if its going up and down. sounds very much like PH swings to be that are stressing the koi. but i would also do more scrapes just in case you missed something. its a hard one to give a yes no answer too sorry mate.

    My fish have been flicking in the evening, did scrapes then got another done by koi dealer all were clear. He thinks that it is when I turn the air down to view them, he turned the air stone off on his main tank and within a minute they started flicking. I think this shows that any difference in conditions can cause flicking but always best to take scrapes and leave nothing to chance

    The tail fin looks like a classic case of stress.. Have you had this fish out of the pond recently?

    Evening all. Out of interest are any of your fish developing symptoms in the way of swimming in a peculiar manner on the surface? Almost As if they are ready to pass on?

    Hi all.
    If your checking the ph ,i would check the kh aswell.If the kh is low that would cause the ph to swing,the kh should be a min of 3 degrees .
    i hope this helps you

    Chris if the koi is taking gulps of air at the surface then heading to the bottom to release it I'm sure that is a sign of excess mucus on the gills and it's there wY of trying to clear it off
    Jedi it looks like stress to me and if scrapes are coming back clear too have the koi been spooked by a heron or something or something changed in the pond

    If the koi is piping then yes its probably a parasite i agree.
    But you must check all water parameters 1st before pulling koi out of the pond.

    Yes my chagoi is always going go up and gulping then going to the bottom and releasing the air but it has stopped doing it now after the pp bath i gave it.

    Sorry to see one of your fish is not looking to well.

    My fish as mentioned by Marc had a very bad internal infection also stress which led to the fish having lock jaw. the tail looked very much like yours is the vent swollen or anything like that? The fish also felt hard to the touch if that makes sesnse especially on its lower body. I treated mine first with a heat, salt and acriflavin in a seperate tank this seemed to help clam the fish and reduce the redness. I spoke with a koi dealer who said this will help but what I really need is 2 injections of baytril, I was very luck to get my hands on this and now the fish fingers crossed looks like its going to make a full recovery.

    The biggest problem is getting the baytril vet only I'm sorry to say. so maybe speak to your local vet as I did and see if they are willing to help you, I learnt how to do the injections from watching videos on line.

    God luck mate and I hope the fish makes a full recovery!

    its only stress either water is not right or parasites.
    i cannot stress enough how important kh levels are.
    your ph will swing that will cause stress,and cause ph crashes which koi dont like at all.
    Then in the end your filter will die because you have no carbohyrates left in the water for your filter bacteria to feed on.
    all the best pete
