Cardinalfish has cloudy eyes, white spots, fin rot. Please help ID!

[DaReef]

Hi everyone, my ochre-striped cardinalfish has had cloudy eyes for quite a few weeks now (originally in just one eye, then spread to both). One of his eyes especially looks quite bad and I'm not sure he can see so well out of it. Additionally he has white spots on one of his sides (shown in pics) and his fins are fraying. I initially tried feeding him food soaked in kanaplex and metroplex, but after 10 days, no change. He ate like normal the whole time and seemed fine, other than the eyes/fins/white spots.
I next tried prazipro as I thought maybe it was flukes. After one round of prazipro, I still see no change, however his appetite is very suppressed now. Either that, or he cannot see the food; it's hard to tell which. I just added the second dose of prazipro today and hope to see more results.
Does anybody have any idea what this might be, or if I just need to be more patient with the prazi? Any help is greatly appreciated, my guy is getting worse by the day and I don't know why

I can't see any issues with the eyes, but the lesions on the right side of the body are pretty evident. Are there any issues on the left side?
I think we need more background info here. This link explains some additional information that can help us determine what might be going on: https://www.reef2reef.com/threads/s...sease-treatment-and-diagnosis-section.775547/

Looks like abrasions and lesions as said. Fighting im guessing.
I wouldnt see a fish itching themselves that hard on the rock

The lesions are only on that side. The only other fish in the tank is a bicolor blenny - I don't imagine there's any fighting, or at least I've certainly never seen any.
I couldn't get a good picture of his eyes, but both are cloudy and one also looks like it's scratched.

It might be helpful to rule out poor water conditions first.
Can you advise
The age of system
How long has it been in the system
What are your parameters
How many months have these parameters been stable.
Fish seem to get a lot of different things including puffy and glassy looking eyes which can be linked to poor, unstable waters.
I’d rule that out first before moving forward.

Yes, I don't think it's water quality but my parameters are:
Temp 80F
Alk 10.5-11
Calcium 420-440ppm
Magnesium 1380ppm
Nitrates generally ~5ppm, sometimes swing up but never higher than 20
Parameters have been stable for at least a couple months

The tank is about 6 months old, had this cardinalfish for a month and it's always seemed really healthy (eating a lot, swimming normal) until recently around the time it's eyes started getting cloudy.
