I think we may be having the same experience. Over two months later my orange back is still alive and eating. I would say he is growing or fat. His side definitely is not coloring back up but I think it's got something covering the tissue. I have experienced uronema in anthias before and it is always a terrible ending. I have have never seen it in a wrasse.
Here is a couple pictures of the current speciman. The anthia that is in the tank is qt is fineand had been in my dt for over a year before banishment. I have been treating with a couple different meds but the nfg got here today so a 50% water change and then treatment tonight. Also moving anthia to lower qt tank which had a anthia with uronema 6-7 weeks ago. It's been uncirculated and unheated, uninhabited so hopefully it's low risk.
How did you recover your fish? I'm more concerned that since these two Wrasse have particularly large scales how long/when will they grow and go back to the proper color?
If I recall uronema does not need a host and can only be killed by certain strong meds or bleach the tank.
If it is in fact uronema in my first Wrasse and it was not killed/cured then it's a likely scenario that I introduced a bad thing into my dt. Hopefully not.
