The usual gamut of questions...
Tank size
Water parameters, NH3 NO2 NO3 PH, temp (need actual test results)
Filtration
Established tank
New tankmates/decor
Prior/recent history of illness disease
Current illness/disease symptoms/duration
Size/age of fish
Tankmates
Cloudy eyes can be caused by a number of things,
High NH3 or NO2... Need those actual test results.
Bacterial infection...
Worm cataract... I've never dealt with it and not sure how to.
Stress/water quality...
These play major roles in practically every illness/disease/parasite.
Treatments,
Pristine water parameters.
My first choice is a combo of Melafix & Pimafix, for problems caught early these are usually sufficient by themselves IME.
I would use them in conjunction with a actual medication if used/needed.
Medications...
Paragon, Paragon II, Maracyn, Maracyn II, Ampicillex, Furan II and Neosulflex...
I recommend either increasing dosage and/or length of treatment above the manufactures recommendations by half.
If you can get some medicated food (antibacterial) into him that could help.
