Hi oscar lovers, I have a health problem with my oscar.It seems to have a type of cateract growth forming over its eye, and I dont know how I could treat this.?
Please help!!!!!!!!!!!!!!!!!!!!!!!! teatu

hi teatu, welcome to the site.
unfortunately, picture is needed to analyzed your
problem. if it is a blurred outer layer, your fish
is probably suffering from ammonia/nitrite burn.
water parameters should be posted. for the meantime,
i suggest you make large water change immediately but
do not wash your filter.

poor water conditions usually result in eye problems as paul pointed out, what are your water test results.
