Lyretail Anthias Feeding

[Blue Ram]

Could any members on the site currently keeping these fish in a reef setup please post some comments on what you are feeding them and how often. I'm a bit concerned that my 3 females/1 male are not getting enough to eat. They don't seem particularly interested in mysis shrimp or any other frozen food I have been feeding the rest of the inhabitants. I saw a suggestion to get some live bottled copepods to feed them.
