OP hasn't been around since 2012, so I doubt he (or she) will mind ....
I am sure there are plenty of other folks here with more hands on experience than I, but I have kept many different species of anthias. Assuming you have plenty of swimming space and are able to feed at least three times a day, I'd rate Bartletts as the easiest (they will eat pellets, but are chippy and you often you end up with multiple males), followed by Lyretails (though they can be quite aggressive too, winnowing themselves down starting with the lowest member in the pecking order), then squares, bimacs, and dinar. I'd rate all of them as eminently keep able. I tried Purple Queens some years ago and would rate them as almost impossible to keep longterm. I have literally never seen anyone keep them sucessfully. I would love to try Ventralis, as I think they are the prettiest of the lot, but I simply cannot meet thier temperature requirements, so pass when I occasionally see them. Time will tell on these Evansi. Clearly easier than Purple Queens because all five of mine are eating, so I'd be inclined to put them somewhere in the middle as far as easy-ness is concerned.
