Orange Shoulder tang; disease, or natural change?

The fish is in a 30g now, and she/it is just over an inch in length. Eventually the fish will be going to a much larger setup, but none of its tankmates wiill be conspecific.

The tank it will be going to has a Red Sea Sailfin, Yellow tang, Hippo tang, foxface, kole tang, CBB, mandrine, blue chromis, yellow damsels, clowns, and I think thats it.

The fish will be moving in around 6 or 7 months to what I hope will be a 600g+ system, if not a 1,000g, assuming I can find a suitable home to do this in.

I just worry that the fish is changing too young, as its still so tiny. Did you take photos when yours changed?
