Looks like a Mimic Tang or a juvenile Lemon Tang, to me.
I think you nailed it. I found this:
"The Mimic is peaceful and has flowing silk-like fins in contrast to the typical tang stiffness. The soft yellows of the juvenile makes a beautiful addition to any tank. The yellow eventually gives way to a dirty transition into the darker blues of adulthood, which are truly drab in comparison to the colors of the juvenile. "
and that exactly described him, especially the silk-like fins.
