    Question Koi Issues - red skin and 1 bloated

    Good evening,
    I decided to check my fish this afternoon as I am planning on visiting cuttlebrook on wednesday to look / purchase some new fish for the summer. I have a few Koi with carp pox but these two koi seem to be in a less than ideal state.

    The black and white one has pink under its white, although is still feeding and doesn't seem to be sulking, flashing or anything like that.

    The assagi feels bloated to the touch. Eggs and also has pink under its white. It also appeared to be very slimy in comparison to other fish.

    I have done some scrapes and I haven't found anything. There might be something there that I am missing but nothing is jumping out at me.

    Any ideas moving forward?

    Water tests have come back at Ammonia 0, Nitrite 0 and Nitrate about 30. Nitrate is about 30 in my tap water.
    I am running a Drum filter with a K1 moving bed and a constant trickle into the pond.

    Pictures:

    Don't be disheartened about the lack of replies - someone who's experienced this will come along eventually.

    Red rashes can be parasites (secondary infection), bacterial, water quality or even UV related. I'm not sure how to pinpoint which.

    A scrape would probably be the first port of call to see if you can find anything under microscope.

    What were they like in the pond before netting, bowling and scraping? I ask as the experience of such can be real stressful particularly if the fish isnít used to it, some fish cope better than others.
    Ifthe water is good and there is nothing showing on scrapes, the fish are behaving normally then;

    Waterwise;

    You donít mention KH or pH, is there possibility the pH is swinging? This can cause the fish to flash or sulk at first and last light? Test of pH and KH can rule this out.

    Is chlorine or chloramine getting into the water?

    Do you use a decent carbon filter for topping up or rely on dechlorinator? If you use a filter then have you tested the output with DPd4 tablets?.

    There could be another pollution issues but cover the basics first.

    Looking at the pics I am not convinced the issues are from the same cause.

    I would guess the Doitsu could be over heavy with eggs or potentially has an internal issue.. That is a guess. Really need a view from the top of the fish.

    The shiro looks like straight stress or the results of flashing.

    Options wise try and get to the root cause by some more testing.

    Immediate term, potentially you could look toadd a light dose of Chloramine T at say 1gm per 100 gallons for a couple of days (UV off) to try and mitigate the prospects of bacterial infection setting in..

    Update:
    I done some more scrapes today and I actually found some flukes. This is the first time I have ever found anything so quite chuffed on that front.

    Hi DaveJ,

    Thanks for the reply. I must admit they were quite slow at come up for food. Especially now that I have put some Fluke Solve in. 6 hours later and they have all perked up.

    Your right, I didn't check PH or KH. I will try and do these tomorrow. I trickle in through a carbon filter and I do add Sodium Thiosulphate too. I will order some DPd4 tablets to make sure.


    I will do some more scrapes to make sure there is nothing else, but will tackle the flukes first.

    Whilst flukes can be a real bugger to get rid of, I'm glad you have found a potential cause.

    Lets hope the Fluke Solve does its job.
