Help, I just noticed today, there is a small whitish spot on my gold nugget. I don't think he had this before and I've been staring at it to see if it was just the glass of my aquarium giving off that cloudy look on the spot, but I don't think it is. I think it is on the fish itself. He has been acting normal and swims around and eats. Does anyone recognize something like this and advise of how I can take care of it. I have some angelfish and a king tiger pleco in the tank and everyone else seems fine. Please help!
Below is a picture of him and I have circled in red where the little spot is.
