Whats on my tang

[AndrewG99]

Hi everyone, I bought this yellow tang yesterday from my lfs, I have noticed a slightly discoloured patch on his bottom fin. He is eating good already, picking at the rocks, eating pellets and also frozen foods. He doesn't seem to scratch at the rocks and seems happy and swimming up to now.
My levels are: salinity 1.025
Ammonia:0
Nitrite:0
Nitrate:5
Any advice would be much appreciated.
Thanks in advance.

I'm having difficulty seeing what you can. I see a little minor fin damage on both the dorsal and anal fins. Any other fish in the tank with it? This damage may just be a result of moving it into your tank.

Heres a better picture and one zoomed in, the zoomed in one makes it look white but in person its more like the second picture. its currently with 5 chromis but was housed with a few different tangs at the lfs for over a week.

O.K., that helps. The rough surface indicates that this is likely Lymphocystis, a self-limiting viral disease often seen in newly acquired fish. It may spread to other fins on this fish, but will rarely spread to other fish in the tank. It will usually go away on its own in 6 to 8 weeks. That said, without a comprehensive quarantine method, this fish can easily develop more serious issues, so keep a close eye for white spots, reduction in feeding response or increase in the breathing rate.
