hi can anyone help i have a breeding pair of oscars one has a cloudy eye what can i do 2 clean it up i done a water change

You need to test the water and make sure that's okay. Since it's only one eye, can you rule out physical damage? Post some photos if possible. Tell us what you feed your Oscar and how big the tank is?

Apart from that, it's difficult to advise you until we know a little bit more about your situation.

As OFL says test your water conditions for ammonia, nitrite and nitrate.

If the eye is only cloudy then i would treat with large daily water changes followed a daily treatment of an anti bacteria liked myxazin.

If the eye is bulging as well as cloudy i would treat the same however the outlook is not so good(from my personal experience)

Hi and welcoe to ofl.com nothing much i can add as the experts have allready covered it.

my tank is 4ft the ph 6.0 ammonia 0.50ppm nitrite 0ppm nitrate 160ppm the fishs are about 14inches but only one fish has this cloudy eye and a bit of fin rot now i have added some tetra goldmed like the pet shop told me 2 buy i will do a water change when i finish writeing this reply thanks:( i feed them on hikari gold and staple and some prawns mussels:(

This has been answered in your thread in the emergency forum. Lots of water changes until your nitrates are below 40. Your ammonia should be zero, are you cleaning the filter often enough and do you have enough filtration (should be rated for a tank twice the size you have)
