Orange Shoulder tang; disease, or natural change?

[michika]

I'm leaning further towards a color change now. Its face is a slight bit darker today.

I'm aware how quickly it will grow, and I actually chose the fish for its adult colors. I wanted something to contrast some of my other livestock choices. I have plans to move the tang to a much larger tank once its a bit bigger, stronger, and more likely to thrive in a larger environment with much stronger currents and flow conditions.

Do you have an orange shoulder tang?
