    Breathing issue?

    A little concerned with the fish breathing at the bottom. It's true he's treading water as there's a waterfall current to the left that sweeps right under the lilies. However he seems to be mouthing where as the others seem to be just more relaxed.



    The pond had an impromptu (accident) water change of about 50% last weekend. There's two airstones running in the pond. Just waiting on my new test kit to be delivered (today I hope) and I can check the water stats. I may still have a nitrate test in the old kit I will see.

    Just concerned.

    To me they all seem a bit lethargic and not swimming around much.....is that their normal behaviour ?
    Plenty of oxygen going in the pond ? lets see what the others think

    The sun is out and they will snooze in the sun but I think I may invest in a microscope ahead of the new pond.

    Normally they’re a little more active searching for food etc.

    Something not right with all of them there mate.

    Mucus coats possibly look on the heavy side as well, that I can see.

    Time for some scrapes.

    The NT labs test arrived:
    NH3 < 0.2
    NO2 <0.25 (0.1 I’d guess)
    NO3 <2.5
    pH 8
    KH over 9 drips > 160ppm
    GH over ~12 drips (we have very hard water)

    The fish at the moment are happily eating, even actively rummaging around for algae and on the bottom (and they're busy sunbathing again - they all do this when the sun is out, eyes under the lily pad) so I'm concerned but they don't seem to bothered at the moment (just wait till I try to catch the blighters!).

    So I need a new net. I couldn't get close to them however I did manage to get the small existing net and from the water from that I found this on one of the slides.

    It has all the hallmarks of flukes without the head crown of kill flukes or smooth crown of a body fluke:

    What magnification is that on?

    Was it wriggling?

    200-400x IIRC.

    It could switch into a swimming mode.. seemed to use cilia in it’s head then was stretching around.

    I’ll try to get a proper net tomorrow - then I can actually do a proper scrape.

    I think that's a normal pond critter - safe and harmless based on research.

    So I’ve tried scraping two fish - both don’t seem to have any mucus coming off on the slide nor do they appear to have any slimyness.

    I did catch a tench at the same time as the orchiba.. the little git soaked me!

    I'm waiting for the rain to stop and then I'll see if I can catch the Rin.. for such a large fish it's really a scaredy-cat and disappears under the others if it can.

    As a couple were appearing a little, well "meh" and mouthing food. I took the executive decision to Flukesol - just 40ml in ~1700l. Suspension into a bucketful of pond water spread evenly over the pond and water fall. The issue is I don't know the precise capacity of the pond (it doesn't have straight sides nor is a known model.

    Initially they ran around and headed under the waterfall. The large orchiba is happy as larry and continues to be chilled out and the rin was making a jerk in the middle of swimming as if something was biting it's side. (I've seen this fish flash on the side too but infrequently).

    Now they're all appearing reasonably relaxed again. No sulking at the bottom although they are skimming the surface (I assume O2) which is new behaviour even with two air stones and the waterfall adding a load of oxygen. My gut feeling is that the pond with the fish and being in direct sunlight may be starting to reach an O2 limit for the stocking which makes me want to crack on with the new pond. I may order the XP80 ahead of time but that's a little over-kill for the pond size.

    Will keep an eye on them, although they seem a little more active overall I will see tomorrow and back to sunbathing using the leaves as sunshades but they're rummaging around and eating.

    Went to feed them today:
    a) they were hanging around at the top looking through the plants.
    b) the drum waste bucket was almost full.. so there's been a bit of rummaging for food around during the night.

    Feeding them - almost had a fight for the food. Even the tench in on the act on the surface. The ghost was cruising around on the surface, it seems he has a new found confidence. The rin wasn't anywhere to be seen however just a little late to breakfast and the Lilly pads started moving the mouth appearing looking for food. The little male has become much more active and is no longer mouthing food. In short they seem more energetic, will keep an eye on them after day three to see if they need a new dose.

    Sounds positive nick.

    Ideally though you want to get a decent scrape.

    I used to really struggle getting scrapes and decent amounts of mucus, especially when working alone.

    I since realised it's a lot easier if you flip the fish upside down against the side of the bowl where it will stay still while you scrape the underneath. Since doing that my scrapes have been much better.

    A good example of it is if you search koi diaries on YouTube from around 2 or 3 weeks ago. It's a very long video but around half way through he scrapes his chag this way and it's a good demonstration of being able to single handedly scrape whilst holding a camera!

    I agree - not only what is the issue but how many equates to how bad the infestation is.

    I saw his video and tried that - he's also sedating them in the bowl. I'll attempt to get the Rin upside - which should prove a challenge!
