Desjardini Tang with strange marks

[Dbichler]

Anyone happen to know what this could be on the start of his fin?

Could just be scrape marks as the fish wedges into or against rocks at night to sleep. Keep an eye on the area for signs of infection: white filmy area, redish or open sores, or necrosis.
