Food For Corys

currently i am feeding my peppered cory sinking tablets called, auquamaster cory tabs. just want to know is this the right sinking food to feed them and Any other types of food i can feed them? here is an attached picture of the sinking food.

Mine eat just about anything that gets offered....froz bloodworm, flake, tropical tabs, algae wafers, shrimp pellets, live brine shrimp.....haven't see them turn their noses away from anything except freeze dried bloodworm (none of my fish will eat it).
