Naso Tang not eating

[Philnashbass]

Anyone had experience with sudden shrunken belly and regurgitating Naso Tang?
I'm concerned with the sudden change. I've read a number of blogs speaking about potential worms or kidney problems common in Naso's.
Let me know if you have any ideas. I can quarantine him but I need to know what to treat him with.
Thanks,

I have done this to my discus fish when they began showing difficulty and it worked.

If you can try to gather some fecal matter and examine it under a microscope. I believe 1000x would be enough to identify masses of cells.
Draw pictures of what you see and then hit google and search images. This can identify precisely the pathogen affecting the fish. Having accomplished a more exact  treatment can be tried.

I know it sounds clumsy and difficult.
