Simply Koi and More Koi

i have a 70 cm plus koi that has stopped feeding for last 2 weeks . i have checked for parasites twice and both times i did not find one parasite and hardly any mucus on each scrape . this koi is acting normal in any other way but is just not reacting to any time i feed the koi it just swims under neath the other koi . i havent checked inside the mouth but i guess that could be the next step. any ideas

Hi,

How is the fish behaving and has it ever done anything like this before

Have you tested the water and is this all OK

Has anything changed or have you done anything different recently

I have you also looked in the gills to see if there is any infecion?

Regards Geoff

hi thanks for the replies. at the weekend after 3 weeks of not taking any pellets i decided to salt bath the koi. coincedence or not the next day the koi returned to feed on pellets .as for water checks they are all spot on and as said the koi seemed ok in every other way .must admit the next idea was to check the gills and inside of mouth so happy to say every thing seems fine again
