Sailfin Tang colors

[Reefnut2010]

So upon inspecting my Sailfin and comparing to pics on the net, I notice some Sailfins have more yellow lines and a more speckled face than others. Are they Desjardinii hybrids or what? Why the difference in coloration? Why do some share markings with the Desjardinni and some don't? Or am I just imagining the difference:crazy1:.

I would think they are just color variants....

My Indo Pac sailfin changes his color all the time and is extremely variable, Mine has a lot of yellow on his fins and body, not as much as the Red sea variant but a lot compared to most sailfins
