Absolute amount of food consumed per day is what's important here. Example: If your anthias only eat one or two mysis shrimps per feeding, and then refuse any more, then yes, 3-4-5 feeding per day will be required. If on the other hand your anthias are gluttons, and cram themselves full of mysis to the point they have a marble shaped belly, then sure, you can easily get away with one feeding per day, maybe even less. So really, just saying how often one feeds per day doesn't tell you much
