If you decide on anthias,go with bartletts or lyretails.Those two readily except any meaty food such as mysis,cyclopeeze,rod's food. etc.Those do fine singly,pairs or more.Either all females and no more than one male.
You will need good skimming and the time to feed them.Because of their metabolism and their constant grazing on plankton in the wild.Multiple feedings(3 times a day)is usually needed.Make sure you system can handle it.
