Thread: White Mucous

  1. #1

    White Mucous

    Hi all

    My pond has been running for almost 2 months and was stocked with 4 carp that I re-homed. A koi, ghostie, mirror and common carp straight away with evo aqua filter start

    All seemed to of been going well until yesterday when I noticed this faint white mucous on my common carp which today has very quickly turned into the attached pictures. I fed them a tiny bit this am and the carp are all acting normally.

    Water tests at 6pm last night were:

    Ammonia: tiny trace 0.02ppm
    Nitrite: 0.1ppm which has been constant from the start
    Nitrate: 5ppm
    Kh: 7drops & ph 7.8

    I added 2 new fish a kohaku and ochiba from a breeder last Friday, these 2 fish the koi and ghostie seem absolutely fine but I just noticed my mirror has slight signs of the mucous today. I did over 10% water change 2 days ago and also isolated the draco drum soloum 16 for an hour or two as I piped in an air source heat pump that is not yet running but the water is going through it..

    Any ideas what I can/should do please??

    This is all new to me. Thank u

    Adam

    Not that easy to see in the pics but it looks like a bad case of white spot.

    Have you got anyone close by, who could help with a diagnosis and treatment?

    Thanks for reply. I've just rushed into my local world of water before they shut as I've been working all day and they've advised to treat with FMG mixture treatment. Without a scrape they cannot determine for sure the best medication

    Unfortunately I've just got home and the fish is clamp up on the bottom. All other fish are wanting food as per usual.

    Hi, I’m no expect but to me that looks like excess mucus. White spot would generally look like grains of salt on the fish how I understand it.

    Whit spot


    It looks like it has been rubbing its head and gills.

    I personally would not recommend putting in MGF when you have no idea what you are treating

    Excess mucus and rubbing could simply be if you have done a large water change and have not dechlorinated the water..?

    Where are you based? Someone maybe local and willing to help

    Hi Mike, thanks for the advise

    I'm in Finchampstead, near Wokingham!?.

    I did around a 15% water change Tuesday but use a evo aqua detox dechlorinator and run it at around 3ltrs per min to make sure its getting all the nasty stuff out..

    I haven't added the FMG mixture yet and have put another water change on after doing my water tests again. The results are the same as yesterday so nothing is rising..

    A scrape will confirm, but I’ve seen white spot as bad as that on a showa I bought a few years ago. It was spotless and from a koikeeper I trusted. Within 5 days it looked like the above and a scrape confirmed white spot. Sometimes moving fish sparks it off apparently.

    My largest koi that died a few months back was covered with it, just like in your photo. It was very quick, fish looked healthy and fine on the Saturday morning and was dead by the Tuesday evening..

    hope you you can get it sorted.

    Oh dear sorry to hear that.

    I'm at a loss what to do, he is not looking good at all now. Just sat near the surface. :-(

    I think i'm going to have to try the FMG as it says it fights parasitic and fungal infections.. its got to be better than doing nothing surely

    Hey Ashy,

    For your nitrogen problems at the start, I'd suggest this product. I used it this summer during a mini cycle. Cleared it up straight away. I picked it up from a Maidenhead aquatics.

    If it's not whitespot, then probably excess mucus.

    I stocked 5 mirrors from VS fisheries in February (i had no choice when they were delivered, thats just when they harvested them) and they all looked pretty manky with lots of excess mucus, fin rot and the odd ulcer from excess rubbing flashing within a short space of time.

    I think that was caused by a combination of new pond syndrome, stress of moving and colder water temps suppressing their immune system.

    Fortunately once the water warmed up they eventually all healed up and have doubled in size over the summer, so can't have been too badly affected.

    If it's not parasitic, then I would be prepared for them to get worse before they improve.

    I found salting the pond on a short term basis helped them out, not just to heal but to protect them from nitrite spikes. If you go down that road then read up on using salt first if you've not used it before.

    Just for reference my Hi Utsuri Presented exactly like that which was confirmed with a scrape as whitespot.

    What a dear little face that koi has got. I agree, that if he's now sitting clamped up then something is very amiss and you've got to take action. Not sure how large that fish is, or what quarantine facilities you have, but are you able to isolate the fish and treat it immediately away from the pond just to see if you can get it to turn a corner rather than risk stressing your new system with FMG, which is going to knock your maturing filter back some?

    Problem is presuming it’s whitespot highly likely that the others will go down too, so whole pond needs treating really new filters or not?

    Thanks everyone for all your replies.

    Unfortunately I'm not able to quarantine him or get a scrape done until the weekend as I'm working away tomorrow and dont have the kit readily available to do either.

    His condition has worsened so quickly over the last 24hrs that I decided to add the FMG about an hour ago. It might be a mistake but I feel if I didn't try something now he might not make it to the weekend. Fingers crossed

    It's so hard to know what to do in such circumstances, I really feel for you. Personally, given your situation I think you've made the right call. Keeping everything crossed for you and your fish. Keep us posted on how things go.

    Got home from work today and the common seemed quite happy and up and looking for food. Still covered in the mucous but it doesn't look as angry if that makes sense..

    Unfortunately my mirror now seems to have the mucous spreading on his head but nothing like the common yesterday...

    I fed all the fish a reduced amount but to my dismay the common started shaking his head and spat out the food and almost looked like he was choking :-(

    Oh dear. Clearly an outbreak of something then. You absolutely need to scrape and scope.

    What FMG have you used and at what dose? Do you know your pond volume accurately and have you got your UV off?

    So my pond is just under 10000 litres and yep I remembered to turn the uv off. I dosed half the bottle of the below FMG as it should do 180000 litres.. the water has gone proper blue
