Hybrid Achilles Fins trouble!

[Gimplar]

Ok, this is wierd as heck. Tonight i was switching out my old sump for a new one that i bought at FAOIS, which went horribly cause it didnt fit through the back or the doors, so i ahve to wait til i move, but my hybrid achilles/goldrim tang top and bottom fins went from black with blue trim to black and like orange/yellow splotches(big splotches too) with blue trim. He seems fine and is eating, all corals are doing good...im really confused and this had to of happened wihtin a matter of 3 hours...

Can you post pics?

Did the body color temporarily change as well?

nope the body didnt change as well, i know fish can change their colors to an extent, but i had never seen a fish do that before where they made their fins look spotchy, it looked like his fins got bleached on certain parts with that pale yellowish look, and whats even wierder is that it dissapeared by this morning...strange.
