Why is my flasher wrasse hiding?

[ASIN28]

Hey all,
So my flasher wrasse had been pretty active all day had him for about 3 weeks now, all water parameters are within check. Between today and yesterday he’s just been hiding and no other tank mates seem to be bothering him either. I don’t notice anything to worry about on him, I just fed he came out of hiding but didn’t eat like he normally does. Is this normal behavior for the flasher wrasse
any advice?

Have you added any new tank mates recently, or changed anything else? I have a flasher wrasse that thinks he's king ding-a-ling since he was the first fish in the tank, and as I was adding fish, he would sometimes throw a fit and go into hiding for a while. If you've spent a lot of time with your hands in the tank this might also make him moody.
