Scopas tang diagnosis

[Dice750]

A bit of background, Scopas has been in qt tank for 2 weeks now. At first he wasn't eating pellets nor nori so I started feeding frozen brine shrimp. That's all he would eat.

After a week of feeding brine he started getting very shy and would never come out of his PVC home, barely even to eat. I started wondering if my params were in check, did a quick test, they were through the roof: 0.25 Ammonia, 0.25 Nitrite and 40+ Nitrates. I had bought a Seachem Ammonia Alert badge to monitor, clearly that thing doesn't work.

I took him out immediately and did 100% water change. Has been 3 days since that happened and he's now more social, eating nori and some 0.5mm NLS pellets. However I noticed some white spots on him after the incident and was planning doing TTM starting tomorrow morning. Now this morning I noticed what looks like a white flesh wound on his side. Any idea what this could be? Is it related to the white spots? What would be the proper treatment?

Params have been 0 ammonia, 0 nitrite and just under 5 ppm nitrate since 100% water change. Thanks.

Maybe look up uromena marinum and/ or tuberculosis ( mycobacterium marina ) !

I'm hoping for you it's neither....
as they are quite annoying and difficult to treat.
The first is a parasite sensitive to formaldehyde , so dips in this wonderful carcinogenic treatment.
And TB is sometimes cured with antibiotics if caught early ...
Good luck

* mycobacterium marinum ...[emoji35]auto-correct

Thanks, I started treating with EM powder as that is all the LFS had in stock (my best guess is that it's bacterial). I'm now starting to wonder if it might be a burn mark from the heater... He usually hides near the heater, anybody ever seen a fish get burned by a heater?

Maybe try nitrofurazone. If it was earlier in the process of being captive I would lean towards ammonia from shipping. I see it a lot in Powder Blues. It starts out with a little off color and then develops into an open wound. Left untreated they rarely recover.
Not saying tangs can't get uromena but I've never been able to confirm a case on tangs under a scope in 5 years of looking. I've seen a lot on other fish.

My gosh I think you're right I've seen a lot of chromis and dwarf angels most likely with uromena ... Tangs fox faces heniochus and other butterflies had TB.
