The fish guys on here will need a bit more info. Age of tank and how long have you had the Gem to start.

Known as thumb print is often bacterial and fish should be placed in a separate treatment tank and treated with Seachem Neoplex or Kanaplex which is a broad spectrum treatment

Is it on both sides of the fish? Gem tangs develop a stress pattern that looks like this, but would be on both sides, about equally.
