So I have a pond, with a dozen or so fish, 2 of which are ghost koi, they are maybe 3 years old and well over 12 inches long.
Now I don't know an awful lot about keeping fish, but the pond is maybe 5 years old and I've had very little trouble generally except for the occasional bout of blanket weed.
Anyway, one of the koi has jumped out of the pond for the second time, the last time was 2 years ago but I saw it jump out and put it straight back in again, it was fed up for a couple of days but was fine after that.
This time I don't know how long it was out, probably quite a while it was nearly dead, but I managed to bring it back with some nursing in the pond.
That was 3 days ago, its fed up as you'd expect but its starting to collect green fur fungus/algae due to the damage it sustained to its mucus coating flapping about on the ground for hours.
There are a few remedies on the interwebs but they all involve isolation, I just don't want to stress him any more netting him.
I wondered if anyone knew of a less stressful way of treating this condition to give him a fighting chance, I think this fungus will grow killing him slowly without treatment :(
 
Don't know of a specific treatment.
I had Golden Rudd jump out of a pond and die.

I think the isolation is probably sound advice since if the fish has a disease you don't want the others getting it.
May be better asking an aquatic supplier.
 
What you are describing sounds very much like Saprolegnia, an opportunistic fungi that will attach itself to any damage on the fish, be it caused by parasites or physical damage, as in your case.

Every Koi dealer will have a preferred remedy for Saprolegnia readily available, just go to your local reputable dealer and ask their advice.

My personal advice would be a malachite based treatment, or salt. Only down side to salt is that it won't leave your pond without physical removal, ie; water changes.

Yeah, that's what I'd read, the trouble is the separation part, most of them recommend sea salt as a cure but I'm not willing to contaminate the pond to the concentration levels they're talking about.
Ghost koi are generally a fair bit tougher than Japanese koi, but still I don't think I'm going to faff about seeing if he can pull through, its looking like a separate tank job.....:(

thanks guy's..:thumbs:

You need to treat at about 1oz per gallon. All Carp are able to tolerate these levels for a long period of time. Some koi keepers maintain salt in their ponds all year round, a practice I don't agree with.

Marine Salt will be too expensive. Some dealers will sell 25kg sacks of food grade pdv salt.

Ref separate tank: The saprolegnia is now in the pond, it's much better to treat the whole pond as opposed to isolating the fish.
 
Serve with chips and a sauce of your choice, i'd say...

That's exactly what I'm doing now, 5 day treatment, just have to see how it goes.
To be fair, the fish has no right to still be flapping its gills after being out so long.
Its always the characters that do the stupid things.

No amount of sauce is ever gonna disguise the taste of fin rot and green fungus...:p
 
My Mum used to keep them - they were always jumping out and flopping around on the patio...longest 'survived' out-of-water stint was 4 hours, I think...pretty cool - I know if it were the other way round I wouldn't have looked so chipper afterwards...
 
No, he doesn't look too chipper, apart from miscellaneous fins going ropey he has a good side......and a grilled side, he must have been out yonks in the midday sun :shake:
 
what you have is fungus , which is a secondary infection when the koi jumped out it knocked it self and the bacteria that causes fungus has got in so an anti fungus/bacterial treatment is need.
the question is why did the koi jump out either parasites. or more than likely a lack of oxygen this time of year , even if you have a water fall running it is not enough and air should be add via an air pump
 
Thanks Rick.

I dunno why he jumped out, he's done it before but that was 2 years ago, I was thinking he's just a nutter, he's the character in the pond, his brother is identical but with a completely different persona, no other fish has tried to jump out..:shrug:
Maybe it is oxygenation, I always thought that was good too, with all the blanket weed I keep getting.

This is my oxygenation, no matter what plants I put in, the blanket weed turns up and just strangles everything, Clover kills the blanket weed pretty good, but it stunts the growth of pond plants, so I only have this shower.



Its a small pond, only 300gal or so.



so I need a pump and some aeration bricks or something ??

I suspect that no bacteria has caused this fungus, just physical damage.

Saprolegnia is opportunistic and will find a wound caused by parasites, bacteria or physical damage caused by jumping out or sharp objects in the pond. On this occasion, I suspect the physical damage created the site for infection as opposed to a bacteria.

That said, an opportunistic bacteria such as an aeromonas strain may have also found it's way in through the wound and caused yet another infection, so your advice to treat with an anti bacterial remedy also is definitely sound advice.
