Auriga Butterflyfish

I purchased one of these fish today. I already have a clown and a mono something i forget exactly what it is called. So i bought the Auriga Butterflyfish from the store today i acclimated it with the drip method for an hour and a half and then put the fish in. He was great and active all day in the tank. Around 9 or 10 oclock i shut the light off and about three this morning i went to check on something and his body that was all white is now definatly grey and he seems to be moving around a little weird. Do they normally go grey at some point or is that a sign of being sick
