question on green bird wrasse

[basssnake]

I just purchased a green bird wrasse(6 inch) last week online. It was shipped over night along with several groupers( I received them thursday afternoon) that i put all into my 150 gallon aggressive tank. It was a few days before he would come out at all. My 3.5" rectangular trigger(about the same as a picasso trigger) was harassing him by chasing him, so he was hiding a lot. But today he has been out quite abit more. I can't seem to get him to eat though. I fed the tank freeze dried krill this afternoon, and then fed a bunch of fresh deshelled shrimp this evening and there is some pieces still left in the tank. I have actually seen him lying near the food, but he won't eat. I haven't seen him eat yet.

Does it take a week or anything like that for them to be ready to eat after a overnight ship and being in a new tank(especially after being harassed at first)?? The rectangular trigger seems to be leaving him along now, I think. Thanks for any help.....
