Blue Garden Gudgeon black spot on head

[IndianaReef]

My blue gudgeon (Bobbert) has this greyish black discoloration above his eye as you can see in the video. What is it and what can be done about it?

I didn't see anything concerning, it could just be a differently colored patch. If he's eating and active, I think he should be fine

How long have you had the fish? How fast did the lesion develop?

Like 3 months and it probably developed a week or two ago

The elapsed time now rules out the issue i was worried about, as Uronema would have killed the fish by now, so i don't think this anything to worry about.
