So I have had my royal gramma for 3 months now and I noticed this spot right above his eye. He’s been doing fine and has shown no signs of scratching against the rock or looking ill. Just looking the same as always. Just introduced a Midas Blenny the day before I saw the spot which may be what is causing this but I’m unsure. I’m very unfamiliar with fish diseases so I’m unsure if this is one or not. These are the best pictures I could get of it. Look right above his left eye
