I feed my corries the wardleys shrimp pellets as well. They break up into smaller pieces after being in the water a very short time, so even the smallest cories (not necesarily fry) can eat them. I have two peppered cories that are about 1/2 inch or so that love them. I also feed mine frozen bloodworms (most all my fishes favorite), tropical sinking pellets (by Marineland) and algae waffers. I am not sure who eats those, probably the snails. None of my fish pick at them when I am watching, but they are always gone in the morning.
