I have had probably close to a dozen differnet species of anthias over the years and currently have about 8...by far the easiest to feed and keep are Lyretails and Bartletts with one rule,unless you have a very large tank, keep only one male and two or more females..Bartletts, however, have a tendency for more than one male to mature when kept in groups even if there is a male present already and they are aggressive towards each other...Although many of the species are peaceful some are aggressive either between themselves or towards other fish....my male stocky was a terror attacking all other male anthias...my squarebacks are a nice anthias, but just large. My Disbars are peacefull, but are finicky eaters and so are my Randall's. I also have a pair of Sunburts that actually share the same cave...I don't recommend doing so unless your willing to take a chance that they will be a mated pair. The most difficult anthias I kept were my Purple Queens...it took a week to get them to start eating small foods like NutrMar Ova and eventually larger foods like pellets, brine etc..they were doing well eating a few times a day for ten months then one day their out eating and the next their gone.
