any suggestions please-been away for the weekend so fish left to themselves-on taking the cover off this morning one has a number of fungal growths + another is just starting-I have given both a salt bath + treated the pond with a bacteriacide-it is heated to 9C- cannot quarantine as the only other place is un heated -what else could/should i do-tested water + all is well there though one has flashed once whilst i was watching

Hi Rob,
Because a Koi flashes or rubs itself doesnt always mean you have a problem, however, fungus spores are present in the enviroment and infections are usually secondary to other infections, trauma or stress.

You should clean up the infected area and remove as much of the fungus as possible then give the koi a malachite bath at 2mg/l for 30 minutes, once is normally enough, make sure you have air in the bath.

Good Luck!

thanks Mark I will try it ASAP -they do seem a bit happier following the salt bath- will the bacteriacide help -should i tweak the temp up a bit?

Id turn the temp up to around 17 degrees, the problem is the bacteria will multiply, but the Koi will have a better chance of fighting off the infection.

Hi Rob
Fungus is usualy a secondary infection you need to find out what has caused it in the first place or you will be fighting a losing battle trying to treat them. If you have tested all water peramiters ok, I would take a scrape from one of your fish to see if you have a parasite problem.

Good luck

I agree John, I thought I had suggested to have a scrape done in my post, but obviously forgot.

this morning they are much happier- the fungus is gone?? swimming much faster-temp is up + all feeding happily-or am i being too confident here- should i wait for the worst to happen :-\

just keep a very close eye on them chap there is no harm in doing a scrape to see if its clear
