White spot on head

[nomad6]

Anyone have any idea what just sprung up on my blue damsel? I know it could be fungus, ick or lymphocystis, but I’m asking for advice from experiences. He seems happy and is actively hunting I just noticed it a couple of hrs ago. Look familiar?

You really need to take a picture using white light. Can't see anything on the blue image.

It’s white Kessil light… I’ll try to snap a better one but it’s to the right, left side of head above the eye

Sorry, the blue saturation in the photos make it difficult to see anything definitive. Natural lighting may be more effective. The lighter iridescent area seen on the 2nd of 3 photos may be a scratch, or may just be how the scales are reflecting the light.

It looks like it came off I saw him scratching on the rocks whatever it was is gone
