Diagnosis needed - Dawn??

Appeared almost over night. No other signs of anything on other fish. No recent issues. Nickle size, shape, and width. The fish is behaving normally, acts as if nothing is wrong.

440ppm Calcium
1.024 salinity

This is my 180 FOWLR.

A final thought. This is not a skin abrasion. What you are seeing has depth. It is literally exactly like a nickle on the body of the fish.

Nothing out of ordinary was done to the tank? Any newbie added?

How long did you have the majestic?
Any expoure to low pH ?

I purchased the Majestic on July16th of this year. It was in Q for over 5 weeks, added to the display on August 24th. My last fish addition was a Kleins Butterfly, added on December 7th. It was in Q for 6 weeks.

No changes at all. No pH fluctuations that I am aware of. My first thought was also pH, but I test 2 times weekly for pH, alkalinity, and calcium. No unusual changes.

Can you get that fish out of the tank and into QT without over stressing it? That is going to be the safest way to treat it. I will pm you shortly with a list of suggestions for meds...

wow that looks like a crazy damage on that angel. I hope it gets better soon!!

Thanks to Dawn for help in answering this thread. I understand why she asked to take this off line. The topic quickly became complicated and it would be easy for the casual reader to misunderstand the process. I do want to say, however, than anyone faced with uncommon disease outbreaks should consider Dawn a valuable resource.

Looking forward to her insight as I am sure I would have no probelm comprehending the procedure.
It is the another way to learn/increase ones perspectives in fish keeping and objective of fish forum.

Complicated is not the only reason for moving this answer to pm. The medications I suggested are not a safe thing for the average marine hobbyist to be messing with and could easily wipe out an entire tank in a matter of hours if used to treat the wrong illness or if not handled properly. Pasfur has enough experience I think he can handle it, but this is not a treatment method I would commonly suggest to just anyone.

Sorry to everyone who wishes for me to post the details here. All I will say here is that this appears to be a bacterial infection with a heavy fungal growth as a secondary infection, and was likely caused by a superficial wound obtained from a scrape on a rock or something of that nature.

the DOC is back

Nothing illegal, banned med???, I hope. I dont think it is the the infection from wound received from scrape on the rock. Well, I havent come across fish stupid enough to cause such on its own but have seen nemerous injuries from surgeon fish. And I dont think it's that either. Although pic is blur, it does not appeared to have secondary fungal infection yet.

There is another possibility as far as how fish were caught. Something most rule out???

Anyway, good luck with treatment and hope Majestic fully recover very soon.
