Spectrum is the pellet I use. I actually haven't used it much because the other occupants didn't care for it too much, but when I saw the way he ate I gave it a try again. Once everyone else saw him eating it, they gave it a second chance.

I turn off the pumps for a while at feeding. The fish get fed first, then when the lights switch I target feed some corals. Wait a bit, then the pumps go back on.
