I agree with the above. I'd add 4 tetras / rasboras, at least, to each school, get 2 more paleatus / pepper corys and 5 of another type. If you use the correct food feeding the corys is no problem. You can use microworms, soaked decap brine shrimp eggs and micro sinking pellets in very small amounts. Between a little of those foods or any combo of them and cleaning up fish food from the tets, they wil be happy campers. If live food is not your thing, frozen blood worms and frozen Ocean Nutrition formula one or two will work just as well.
