The black spot on the chin ( and possibly the same with the black on his anal fin just look like reactions to where he was probably hiding in the rocks. As you can see in this picture:Both I just now noticed the spot on its chin
The area by the tail is also lighter in color so unless on yours the area is fuzzy or has a raised appearance, it's not something to be concerned about.
