Anthias prefer meaty foods. Frozen food is always best. I fed a mixture cyclopeeze, fish eggs, mysis shrimp, and something else I can't remember at the moment. I fed dry food, NLS pellets and crushed omega flakes, from auto feeder while at work. You will have to make sure that your filtration will accommodate the amount of feeding you will be doing, otherwise, your system will crash.
Lyretails - Caution with these. The most aggressive of the anthias. Optimum success with 1 male and 3 females of same size. The same size because if any of the females are tiny, it will perish for sure.
Randall's - Great choice. Peaceful. Suggest 1 male and 2 females
Carberryi (threadfin) Anthias - Great choice. This was the only schooler in my tank. Start with 5 if can.
Resplendent - Peaceful. 1 male and 2 females would be great.
Sunburst - Doesn't school. More of a loner. Peaceful. Very Shy.
Sunsets - Great choice. Active. Peaceful. Get 1 male and 4 females
Bicolor - Heavy eater. Active. Gets big. 1 male will do just fine.
Ignitus - Peaceful. Active eater
Ventralis (Cook's Island) - Very Hard to find lately. Extremely difficult. Active eater. Very Shy. Mine stopped being shy after seeing all the other anthias eating and not running from me.
Pink (stocky) Anthias - Peaceful. Active eaters. 1 male and 2 females will do great.
Squareback Anthias - Gets huge. peaceful. messy eaters.
These are all the anthias I have kept when I had my 65gallon rimless tank back in 2013.
Other anthias I wish I had were Red Saddled Anthias and Hawaiian Ventralis Anthias.
