Queen Angel Eating - How To Get Them To Start

Hi:

I have an adult queen angel for approximately a week and can not get it to
eat. All the other fish in the same tank are eating just fine (red sea
purple tang, demsels, clowns, cardinals). The tank also contains soft
corals. He is slowly coming out more, but I get concerned when a fish does
not eat. Purchase mail order so I did not see him eat at the time of
purchase. Otherwise, he appears healthy. Tried raw shrimp, and brine
shrimp. Will try formula two next.

Suggestions????
