I have 5 queen anthias, 9 lyretials, a mating pair of bartletts, and a sunburst. They all are fed 2-3 times a day. What they are fed are ova prawn eggs, cyclopeze, pe mysis, mysis, and brine. 5-8 times a day is way to excessive and they will do fine getting fed 2-3 times a day. The ones i believe are the easiest to keep would have to be the bartletts. They eat nls pellets and actually will spawn in the aquarium. Lyretials are easy no doubt but sometimes will perish one by one. My queens were a little bit tricky to feed but once i found they went nuts for ova prawn eggs were very easy. The sunburst is a little more skittish, only eating when there is no other fish around and hides quite a bit. Pink squares are very easy to feed but do require as you know a larger tank and food that is larger in size. Feeding regular mysis is not sufficient enough to sustain proper body weight there for feeding pe mysis and krill are a must. I had a large square back male but gave him away to a 400gallon tank due to the fact i believed he was too big. I have had all of my anthias 4 years by the way and have not lost a single one.
