Naso Tang - Need Diagnosis

[deflux]

Hey everyone,

Got a Naso Tang about 3 weeks ago. He was looking fine, but I noticed that he has these puffy gray spots on his fins. I've scanned him for signs of ich, and I don't see any definitive signs of white spots. He's a fast mover and relatively shy, so it's hard to get a good look at him.

He arrived with a Regal/Hippo Tang, and the Regal is just fine. No white spots, no puff, no nothing. Both very active and both eating well, but he clearly has something. I'd like to treat him ASAP, but I'm not sure what I'm dealing with. I've attached photos, and while not the clearest, they're the best I could get.

Thanks in advance!

what size is the tank? i would get some herbal medicine to get rid of it its most likely a parasite. doesnt work as good as copper but im assuming you have coral and inverts

May be Lymphocistis. Sorry, don't know too much about treatment. Scroll down till you see Lymphocistis.
