Fungal infection possibly?

[Simon Cushing]

Hi,
I have a Bangii cardinalfish I Have noticed above the one eye a form of infection or injury, looks to be white.
He seems to be swimming and eating alright but I can’t tell if it is a infection or injury. Is worth keeping an eye on it Ha! What kind of treatment can I do? Any advice would be appreciated.i have uploaded a photo the best I can get as it’s looks transparency! Could you blow it up on screen?
Many thanks

One cloudy eye is usually flukes. A freshwater dip will confirm
