Agree with most of what has been posted. I like to feed a variety of the prepared foods to ensure good nutrition, and most any sinking food (pellets, disks, tabs) will be relished by corys.
The shrimp pellets food is a very good basic, but your algae tablets are good too; these usually contain some "meat" along with the algae base, and the veggie aspect is good for fish nutrition as it helps the intestines function. I am presently using Omega One shrimp pellets, Omega One Veggie Disks, and New Life Spectrum sinkling pellets .5 and 1 mm sizes. The latter feed the upper fish too, but sufficient also sink for the corys to eat.
As someone mentioned, go easy on frozen bloodworms; once or at most twice a week is the max.
