Midas Blenny turned transparent, should i be worried ?

[pairenoid]

hes usually a dark yellow close to gold
since i got my new lights he looks a bit blue but today his entire body was close to white, even his face, the picture doesnt do justice but he moved to fast.

i was kinda nervous i thought he was dying but he behaves the same

one thing i changed was adding 2 snails, 6 white hermit shells (empty), and a peppermint shrimp

thats all

edit:well that was weird after i fed him he slowly turned back

i never seen him that white before

I think they can change colors just like Foxfaces. When their scared or when the lights just turned off or on they change color. Once everything has stabled they change back.
