Is something wrong with this Angel?

I tried to get the best pictures I could but the circle behind his eye, is this just a color pattern or is it some type of worm/parasite? Only one of my two angels has it and it seems to fade out with the rest of his stripes at night. They seem to have just developed out of the blue

I agree. Looks like a normal pattern. Have you noticed a change?

Seems like a normal pattern to me. My last angel had a spot behind her eye on one side.
