Anthias with Uronema?

Seems I am asking for your help all too often.

Have 5 Lyretail in the tank. 3 full female 1 dominate transitioning female and a subordinate transitioning female (we believe). Started seeing rough scales on the subordinate a few weeks back and thought it was just regular agression as they sort out the hierarchy. That fish seemed to drop out of the group more and more although the scales have seemed worse and worse. She is spending alot of time near the cleaner shrimp.

Is this Uronema? If so can anything be done for this fiah? What about the other fish in the tank?

Unfortunately it does appear to be uronema which is an oval ciliated motile protozoan which causes tissue necrosis as seen on fish. Often scales as you noted are lifted or even fall off.
This can be triggered by low salinity levels as well as excess food waste on tank bottom which this protozoan can feed on as often prevention can be more valuable than cure for this.
You will want to get Quick Cure or even Api General cure which contains Metro. If none, then Ruby rally Pro.
Chloroquine Phosphate will also work but must be used precisely.
Best treatment choice is a 45 min formalin based bath using Quick Cure or ruby Rally then finished in a quarantine tank. Once in QT tank, treat and assure that the parasites have been eliminated before assuming fish is fully cured..

Thank you.

As the fiah is currently in reef DT, what treatment options do I have and how do I protect the other fish?

That does seem to be internal Uronema, but the lesion is much larger than is typically seen. Also, the development time is longer than is usually seen in Uronema. The typical progression is the fish develop a tiny lesion on their side (it grows from the inside to the outside). Within a day or two, the lesion grows larger, the fish stops eating, starts to breath faster and then dies.
This could be Uronema, but it could also be a mixed bacterial infection.
Sorry - but in either case, there is simply no way to effectively treat this in a display tank.

Thank you.

I believe vetteguy provided the treatment proocol requiring a hospital tank.

Would you suggest removing the fish from the display so as to not infect others? Is there a risk to other fish at this point?

Thanks for providing the video - agree with the rest - Its not usually 'contagious' - many tanks have it with no problem. I would consider removing it anyway to a hospital tank - and treating with a broad spectrum antibiotic as well as the options mentioned by Vetteguy and Jay

because of the behavior of Uronema, I would treat fish in a sterile quarantine tank for best chance of recovery

Uronema does not spread readily from fish to fish in aquariums, but because it often shows up in groups of newly acquired anthias or chromis, it may show up in more than one of those fish, making it seem contagious, but that is just coincidence.
