What are your symptoms you have on your Naso? Is it cotton like fluffs on fins or body? Why do you think your fish has this disease?

I did have a Naso tang & a Angel fish in the past that had lymphocystic. Lymphocystic is a virus, I refer to as fish herpes. It can be spread to other fish if the other fish has an open wound. Lymphocystic can be controlled and even eliminated with many factors corrected, such as improving & maintaining excellent water quality, raising water temperature higher, having a low population tank, no stress for that fish and garlic soaked foods. With these conditions above corrected, the disease usually runs its course in 4 or more weeks.

Now, lymphocystic can be easily misdiagnosed and be a secondary bacterial or fungal infection. It's good to know for sure and a picture would help.
