is my Favia sick?

I noticed these white specs on my favia over the last week, especially with the lights off.

when the lights come on, it's less noticeable.

is it sick?

everything else in the tank is fine.

now that the lights are on, the favia is fully enlarged and full of color...the spots have gone away.

it's like this every time when the lights are off.
 
That it looks like that when you take a pic in the dark, but it's actually normal.....
Not trying to be funny, but the pic looks to me like it was just taken in a dark tank so there's no color showing and the spots look like sand....

no worries, bc I thought the same thing at first. it's not sand.

maybe nothing to worry about then if it looks healthy in the "day light"...
 
Maybe the white spots are pests that only come out in the dark to feed? I would try to tweeze one off the coral just to be sure.
