That 'coral food' is much much too large for acropora sp. corals. That looks like something a brain or chalice coral would eat readily though.
For acros and most sps, think bacterial or sub-40 micron in size. Target feeding discourages capture and retention of captured material, even if it is biologically nutritious. In fact, the millepora behavior was almost identical to predation anxiety corals exhibit when parrotfish are nearby.
