HI:
so a little more info please. How long has the fish had ich, did it appear to get better, but then this bacterial infection popped up? What did these white spots look like? since you assumed it was ich.
Ed is right on the money, the cloudy eyes are a sure sign of a bacterial infection, which usually hitchike after the ich parasite does a number to the fish. Most likely you are in low period for the ich. Quick cure is formalin and malachite green, so if you were able to keep a sustained high dose it may have eradicated the ich. I doubt it thou.
What is in the tank w/ the clown? do you have any inverts or live rock in this tank?
Our options now depend on what you want to do
I would seriously consider a hypo treatment (do a search here for hyposalinity) w/ a concurrent antibiotic treatment. We can discuss this later
first things first. More info on your tank, tanksetup, water parameters, tankmates, etc
I await your reply
