    Bulging Eyes and Mouth

    Hi all,

    I have a small Ghosty in my pond that has developed quite an awful case of pop-eye and I'm wondering what the hell has happened and what are the potential causes/ issues?

    It seems to be swimming around ok, however it does favour sulking at the bottom on it's own mostly and I haven't seen it try to eat.

    The majority of my fish seem to be a bit sleepy at the moment, but have started perking up with the gradual temperature increase. Apart from the odd carp pox on a few of my mirrors, they all seem fine and show no signs of disease, apart from this one.

    Water changes are frequent, with ammonia, nitrate and nitrite all low/ not present. Ph is around 7/8 along with KH and GH around the 6-8 region as well.

    I have quite a large filtration system which has a 2 stage bio section. The first after the mechanical stage is a k1 tank and the second is a shower filled with 3 trays of alfagrog.

    I did have a casualty over the winter with one of my small koi developing a nasty case of mouth rot (again). So I'm wondering perhaps a bacterial issue in the pond? If it is, how do I resolve this and prevent it from happening in the future? I don't really want to add chemicals to the water, as I have a few sensitive species and I also don't want to set the bio filters back.

    Any ideas?

    Thanks,

    Forgot to add, it's a 1600l (ish) grow on pond. Been established about a year now and I've not added any new finish since the guys went in last year.

    Trying to help here. But it's a hard one to work out. Trying to eliminate things.
    First your pond may still be in new pond syndrome. Even though your readings are good. Mine took 2 years to properly mature.

    Have you done all tests from the tap as well as the pond.

    Have you tested chlorine.

    Is there enough oxygen.

    How often do you clean the pond bottom
    And is it clean.

    Do you back flush all your pipework to get any decaying debris out.

    Is anything leaching in the pond.

    Do you clean filters out often. And look in them. To see how clean they are.

    Are you over stocked with fish.

    Are you testing for phosphate as well.

    The reason I am asking these questions is I went through a same process as you.
    Fish getting ulcers and fin and mouth rot.
    Ended up building a qt and grow on tank to save my fish. With heat and salt.

    How I save the fish with mouth rot which was bad. And fin rot. Pasted it on to damaged areas after trimming fin. I mixed a pp mix. With teaspoon of PP in a egg cup. With water.Pasted in mouth with cotton bud. I put fish to sleep.
    With water then heated tank to 23c. And salted qt at o.3% of my water volume. Then after a week upped the salt to 0.6%.

    It turned out I had lime leaching in the pond.
    Also I was putting to much oxygen in the pond. And it was stressing my fish.
    Also NPS.

    It took me 3 months to find these problems.

    Have you scraped your fish and microscopes to rule parasites out of the equation.
    Hope this helps
    Fred

    Hi Fred,

    Thanks for getting back to me; definitely a lot of places to start investigating. I've not done any tests from the tap, so I'll look at those.

    It's a pre-existing brick pond that I whacked a liner in with a pump fed filter system; the long term plan of knocking it all down and building a 17k litre raised pond in its place. So it's very much just a growing pond and introduction into the hobby for me, something I've wanted to do since I was a kid.
    I regularly clean the pump cage and pipes put as I have noticed that crap seems to settle there. It is situated partially under a type of spruce tree which has been concerning me, as it dumps all its pines in the pond after a particularly gusty day and I have to fish them out regularly. Perhaps that could be a contributor?

    Pond bottom is quite clean, but I do have a very powerful air pump that probably is too much for the size at the moment. I never really thought that could stress them out, but I have it attached to a variable air tap, so I can dial it back on the line going into the pond.

    I have quite a few fish in it, but they're all quite small at the moment, with the biggest carp being one of my mirrors at about 8". However, it is a mixed species pond that includes sturgeon, tench, rudd and a grayling, so because of the varied feed used, I stay on top of water tests every few days and carry out regular partial changes, especially last summer when it was new and I got carried away with adding fish during that new pond stage.

    The mechanical section of the filter is cleaned every week or two, however I will hold my hands up and admit it was less frequent than that during the winter months because of the weather. In hindsight, that may have been an issue too, especially with one of the koi somehow contracting a really nasty case of mouth rot that ultimately killed it. When I noticed that issue, I did a skin scrap and a scrape around the mouth but couldn't find any parasites, and I'm confident that I don't have a parasite issue in the pond, as the rest of the fish seem fine and aren't displaying any related symptoms (touches wood).

    I'll investigate a bit further from what you suggested and if I don't see any signs of improvement from that ghosty, I'll move him into one of my pre existing QTs, salt treat and hope for the best!

    Thanks again!

    When you do your water changes do you add dechlorinator for the chlorine.
    Most of us on here use ST Crystal's.
    Sodium thiosulphate. If you use filter stage
    Like a 3 pod dechlorinator filter. For adding water. Test with dpd4 tablets.
    To make sure chlorine isn't passing.
    A lot of us on here add ST. Because we don t trust them.
    I use mine just to take metals out the water. But ST for chlorine side of things.
    Good luck with it mate.
    And let us know if you find anything.
    Fred
