welcome to oscarfishlover Carl

You might want to turn your caps off next time you write a message, it is not easy reading a message when it's all in capital letters

Okay, regarding your fish. We need some information, how big is your tank? Have you tested the water for ammonia, nitrite, nitrates and pH? Also, how big are the fish? The cloudy eye could have been caused by trauma since they are fighting, it could also be down to water conditions. Please get back to us with some answers and we can try and help you more

Buy yourself your own water testing kit. If you get the water tested at a shop can you post the actual results

In the meantime do a couple of 25% water changes and add an anti-bacterial like myxazin

sorry about caps

the tank size is 118 x 48 x 68 cm (WxDxH)
the ph is 9
and the fish are just over 2 inch

let me start off by saying that some of the advice we give people may not be to everybody's liking, however, it is given in true faith and with both the fish keeper and fishes best interests in mind.

So down to business,I'd have to go to the fish tank size calculator to work out exactly how big your tank isin actual gallons but I would say it's probably only big enough for one Oscar. okay, you're Oscars are only 2 inches at the moment, they grow very fast and will soon outgrow your tank. I would strongly advise you to re-home three of them. Could you also tell us what sort of filtration you are using?

the filter modle is Tetratec EX 1200 for 200 - 500 Liter Aquarien

Your filtration is good. How long has the whole setup been running for?

sorry got the tank size wrong it is 118 x 48 x 75

the tank has bin running for 3 weeks now 2 week befor i got the oscars
