Large White Patches on Naso Tang

[Brisk]

Hi. I'm still learning about the hobby and I went to one of my LFS yesterday to see what they have to offer. I saw a Naso Tang that has large white spots on the stomach. Are these stress marks or a disease? What do I do to remedy that?

to confirm, need pics under white light intensity as these are a little dark in blue lighting

Those look more like scrapes than stress marks. I’d pass on buying that fish or anything from that tank. Blonde nasos are showing really high mortality rate from an unknown cause, and if this fish has been scraping its side, it could have flukes.
