I did a bunch of research on anthias right before I was going to move to a 65 gallon. There are many different kinds of anthias, from lyretails to bimacs and everything in between.
They generally like to eat three times a day, that's true, but twice is really fine if you're conscientious about it.
Also, I would strongly recommend at least two, a male and a female, as it kind of defeats the real beauty of such a fish to have only one. Three is even better (if you have the space).
Google some good descriptions of anthias on certain sites and you'll get a good rundown of what to expect from each species.
