Fowler display tank has ich

[payrawsa]

Three tangs now have cloudy eyes today. Eyes also look a bit like they are bulging. What could this be, how can I treat it and what happens if left untreated?

I think it is bacterial because it happened as soon as I started copper. Before copper they ich but eyes were normal.

I also believe gem tang is showing signs of hlle and purple tang showing early signs.

On closer look the eyes don't seem to be bulging that much. They could be inflamed from the excess ich they had. Believe it or not purple tang had a lot more yesterday

Let me know what you all think @Jay Hemdal @vetteguy53081

Can you postpone the shipment? It is never a good idea to add new fish to a group of currently sick fish - too many things can go wrong, no treatment is 100% certain or totally without risk.
Of the fish you listed the cowfish and flame angel are two that can be sensitive to copper. I’ve put them into 100% copper right away, but both species do better if you can ramp them up over 24 hours.

I am not really able to postpone the shipment

Copper does not cause bacterial issues. Uncontrolled ich can cause secondary bacterial infections though.

Some of the spots on the purple tang may be mucus plugs, a short term reaction to stressors, including ich or copper. The fish may also still have ich.

I too see mucus plugs and with size of dots - Marine ich

I've maintained therapeutic levels of copper. Achilles tang looks almost like there's powder on him. Nothing fuzzy or bacterial. Just a powdered look. He is swimming into powerhead at times which makes me suspect velvet. Appreciate any feedback @Jay Hemdal @vetteguy53081

That isn’t velvet, the spots are too large. With velvet you get rapid breathing and sort of a glassy look, you won’t see discrete spots. This is either ich and/or mucus plugs.
What copper are you using, what is the concentration and how long has it been at that level?

A full dose is 2.5, and it can take a week to see the ich trophonts disappear….so this could still be ich trophonts or mucus plugs.
