My corals eat a slurry that I make biweekly, made of scallops, table shrimp, salmon, oysters and just about any other fresh seafood my seafood guy has in stock. It's different every time. To this I add mysis and spirulina powder from the health store. As I make this fresh and don't freeze it(kept in the coldest part of the fridge), I then add some activated yeast to help prevent bacteria growth. All of my corals actively eat this, throwing mesofilaments and tentacles into the water column.
