It's could be both ich and stress related. Ich commonly present on wild-caught fish unless it's treated or the fish fights it off. Stressed fish allow the parasite to really take hold and flourish. If the fish is in your display tank it will have to go fallow for up to 12 weeks while the fish are treated in separate tanks (look into both hypo or tank transfer methods and decide which one is best for you). It's always a good idea to quarantine new fish before adding them to the display to avoid having to do this again in the future.
