    Unhappy Fish has film over eyes and can't see!

    Hi everyone,
    I noticed a frog piggybacking on one of my Koi. Didn't think much of it. The frog was hanging onto the front of the fish holding onto it's eyes. Three days later noticed the poor guy can't see! There seems to be a yellowish film covering both eyes. He just swims back and forth until he hits an object/wall, so literally blind. Although there is netting he is still vulnerable to a Heron attack. He's fairly big(about 1Ĺ feet), but hasn't lost weight and seems to be eating plants for the time being. His colour is a bit paler.

    Any advice would be greatly appreciated.

    Thanks in advance.

    Best regards.

    Hi,

    Sorry to hear this. I cannot offer much advise on the eye situation but frogs will latch on and can kill your fish. Had this happen to a few fish in my old family pond. The frogs latched on in the gills as they think the fish is a mate!!

    Hi Mikeh83,

    Thank you for your response. I haven't had any problems with frogs until this year. They've lived alongside each other for about 8 years. There are about 8 frogs at the moment and plenty of eggs. Normally the fish eat the majority of eggs, so that controls the frog population.

    No problem, just sharing my experience with frogs. I dont have any in with my koi but if I did I would likely rehome them.

    Have you done any treatments recently? I am wondering if the clouding of the eyes could be a reaction to a treatment.

    This then could have made the fish more susceptible to the hitchhiker/ sexual predator

    I do fear that the eyes are likely damaged beyond repair if the frog did indeed have its fingers in them Fish has film over eyes and can't see!

    Do please let us know how you get on.

    Others may have better advise for you.

    Mike

    Hi Mike,

    The only treatment I did was to pour some Medifin(Green bottle) into the pond and direct the fish towards the area. I made sure that he swam a few times through the blue cloud that's generated by Medifin. Apart from that, no other treatments and he hasn't had any adverse reactions to treatments in the past.

    Best regards.

    Have you had the koi out and sedated it, this would allow you to check for wounds to the eyes. It's possible the frog has scratched the eyes and this has allowed an infection to get in.

    Do you have any pictures of the eyes?

    Hi Laura,

    I have attached a few pictures. I hope they're clear enough. Apologies if they're not. It was very hard to get him to be in the right place for the photo. Bless him.

    Thank you.

    Best regards,

    WK

    Not the best pics but looks like may have bacterial infection to the eyes due to getting damaged.
    You would need to get it out and sedate it for a better look and diagnosis.
    Thing with eyes is there isnít much you can use on them without causing further damage.

    Laura.

    Thank you Laura and freddyboy for your responses. I wondered if I could put him in the bath and treat him? Fortunately, we have a separate shower in these difficult times, so I can put him in the bath and quarantine him and try a few methods that might work. He is a big guy, so putting him in the bath is the first challenge(without causing him much stress). Hopefully, the water will be a bit warmer than outside which I'm sure will help in regard to reserves(?)

    I did put in Medifin into the pond twice and persuaded him to swim through it a few times. His colours seem to have come back(they were paler at first), and he seems to have got used to life without sight. He comes to the surface at feeding time and eats off my hand. He kind of knows when I lower my hand to feed him, and comes to the surface. I wonder whether he could see shadows? Or maybe senses ripples in water? If I do put him in the bath, what can I treat him with? Is something like Medifin ok?
