I really doubt they would even show up on a picture. I will describe them as best as i can.
The color on the whole oscars head is the same color, its near enough the same color as this oscar i found on google
< It looks like that <
They are inbetween the nostrils and there is one behind the nostrils, there is a group of them in close proximity making a sort of triangle / pentagon shape on the forehead then just 1 behind each nostril a bit further back.
They literally are smaller than a pin prick i was just wondering as i didnt know oscars had anything like this?
