HELP What is my fish sick with?

[Fishtank3]

Purple tang is sick with something, and have no idea what it is. Is in qt with hypo, cupramine, and metroplex. Would like to know what this is though.

Second purple I have seen with bacterial disease like this in addition to a black tang. This has gotten to point of affecting the eyes as well as skin.
If fish is not breathing heavily, you can give it a freshwater dip for 5 mins in water the same temp as display tank. Some causes are:
Stress
Poor water quality
Poor diet
A secondary infection resulting from having another disease

Treatment will be needed ASAP in a quarantine setting with use of Seachem Kanaplex Or if none - Maracyn 2 with added oxygen via air stone and Monitoring ammonia levels with a reliable test kit such as Hanna or salifert brand
When has fish last eaten?
Is it breathing normal or Heavy ?

We’ve been seeing a lot of tangs with excess mucus. That can be a reaction to issues that cause stress. In this case, hypo, Cupramine and metronidazole are all stressful, so all three at once would be extra stressful.
Are you at full hypo (1.009 sg)? If so, that’s redundant to copper and metro. I think you should pick one treatment and stop the other two. Which one depends on timing, copper level, etc.

Yes full hypo, was told my lfs to do all of the above. Copper is testing at .75 on an API test, live in a remote area and was only copper test available locally. It started out with ich, and I think this is now a secondary infection. Would any treatment in particular be best route forward?

Cupramine’s full dose is 0.50 and should not be dosed higher than 0.60. I wonder if that is the cause of the mucus production. There is also the idea that ionic copper is more toxic at lower salinity .I would remove the copper in this case. The only disease it will treat that hypo will not is Amyloodinium/velvet.
