Anthias wont eat

[losthere]

My anthias wont eat. I have had them for about 2 weeks and i havent seen them eat.I have tried mysis, live brine and prime reef. Whenever i feed they just go hide in the rocks like they are afraid of the feeding activity of the other fish which are 2 true clowns and a loubbox(sp?) wrasse. At times when food is in the tank they get excited and look like they are going to eat but just go back in the rocks. They swim around normally, however they are still a little skiddish. They look healthy, no signs of disease or sickness. Any suggestions on how to get them to eat.
