anthias are great fish, some you should stay away from I have not kept this peticular species but it looks to me like a deep water species in which case is difficult keep. They prefer lower light and cooler water, double check the area that it is collected from.
Otherwise anthias are a schooling fish and you should have at least 3 preferrably 1 male and 5-6 females. (they do change sex) You should feed anthias 2-3 times a day with high protein food (pellets and cyclopeeze work well) and have very healthy live rock (lots of pods) they do better with caves and crevices.
