I agree as well............I also wouldn't put them in the display until they are swallowing chunks of food. The notion that anthias won't eat anything that isn't a tiny food is way off base.
They probably have adapted to this in the wild because that's what's available to them, but in the aquarium setting they'll eat much larger pieces. I've seen my Randalls & Ignitus eat chunks of raw seafood as large as their heads. In the past when I had lyretails and bartletts they were the same way.
Before I'd put them in the display, I would want to see them swimming over each other waiting for me to drop food in the tank and then witness a feeding frenzy when it's dropped in.
