Hi all
please shed some light. are cloudy eyes an illness and can it be cured or is it all doom and gloom for the fish. if it is an illness is it contagious ?

this is bad. surely there are others who must have had a similar problem

Hi Gakes

I have moved your post from equipment to koi health.

Could you please post under the correct heading. I had to move almost all your previous posts to the correct category.

Cloudy eyes can be caused by parasites, bacterial infection, fungus or physical injury, but normally it indicates a gram negative bacterial infection which often requires anti-biotics, although a fluke infestation sometimes also causes claudy eyes.

I would check for parasites immediately. If there are none, I will treat for a bacterial infection (Potassium and Terramycin in the food) and monitor all the fish closely for any signs of a bacterial infection like pop-eye, ulcers, swollen body.

If the fish is really valuable, I would send a swob for testing to enable you to decide which anti-biotics to use.

Often a strong dosages of salt rectifies the problem if it not an advanced stage of infection.

thanks and apologies for incorrect category. visibly there are no signs of ulcers, popeye or swollen body.salt is at +- 2kg per 1000L max. should i raise it and by how much ? Is AQUA -201 PROBIOTIC FEED ADDITIVE any good ? as i have 150g in my posession . if not i will get what you prescribed tommorow .
thanks
