Blue Tang with white patch on face

[Pericyte]

Hi all. I have had a blue tang for a year or two now, but I walked into the room and he had a white patch on the side of his face. I will monitor to see if it changes, but wanted to ask if this was something to worry about:

Also, the pic is not the best quality, there are some reflections and smudges on the glass, but I am asking about the white patch around the eye.

What's his diet?

The pic is unclear but I'd personally say MHLLE

Thanks for the quick response Shiv! I had the same concern, but I woke up this morning and his face was totally back to normal! Same this afternoon.

I feed him nori, spiralina, and a mixture of mysis/brine/cyclopeez (a couple times a week I put selcon in it).

I had that happen to one of mine, as far a I could work out it was caused by contact with coral. A sting of sorts, it happened a couple of times when he tried to squeeze in between coral.

Good to know, thanks Shane! He loves squeezing between rocks, so it makes sense to me.
