Anthias are known to eat small crustacians like rodifers and cyclopeeze. I had a sunburst who refused all foods i gave it, as they are known to do. I have a lyretail who eats anything i put in the tank except algae sheets. I have a queen anthias known to refuse to eat like the sunburst, and i had a heck of a time getting him to eat, but he finally took some cyclopeeze and rodifers, he will also eat live brine, but i don't like feeding him that more then afew times a week.
