Help please.

Kinda looks like velvet but doesn’t have the sugar Liek crystals of velvet. Some type of fungus? Any info would greatly help. Currently in QT with copper and fish mox

Tail nipping from aggression and likely Another tank or other fish
Identifyi the culprit and isolate it temporarily

I know for a fact it’s not aggression. It’s some type of disease

Frayed fins like on the yellow tang’s caudal fin are almost always indicative of aggression. The pectoral fins have a white coating that looks like lymphocytosis, which is often a stress response.
I’m not seeing any spots on the body. Does the sailfin have anything? It’s hard to tell in the pictures.

Now that I see other pics, this is ich and possible tail rot
what copper level are you using ?
Also see bacterial -you can add seachem kanaplex and added aeration with focus on water quality

Let us know how you know for a fact please. It will help to know

He was in the tank by himself when this started developing. Added him to a QT I had running for another fish. So no other fish could have bullied him as he had no tank mates.

Yes sail fin has similar issues. Just fins aren’t rotting like the yellow

When I see fish that look "tattered" and aggression can be completely ruled out, the differential diagnosis is flukes, or possibly a secondary bacterial infection.

If your copper is an amine-based product (coppersafe or copper power) and you have a known level of 2.25 ppm, you can rule out protozoans like ich or velvet (but copper takes at least 3 days to start to work). Velvet causes rapid breathing - in all cases. If you post a clear video of the fish, I can evaluate their breathing rate.

External Fungal infections are very rare in marine fish (common in FW fish though).

So I initially thought flukes. But they have been in cooper for 2 days now and those spots really haven’t come off. The yellow tang got worse once added to the cooper QT. I will try and get some clear videos

I hope this is clear enough.

I couldn't see much detail in the video, it had some weird "glow" to it. The YT does seem to be breathing fast. Are its eyes cloudy, or is that a function of the video?

Copper doesn't kill flukes, and it takes 3 days at full dose to really begin to stop any protozoan issues.

Be sure that the ammonia level in this tank is kept below 0.50 ppm (the copper contains some non-toxic ammonia that interferes with some ammonia tests).
