Wow! The ammonia got really high, but it did go down quite a bit. Still not to the optimal level of 0 ppm. Tell your wife that fish are beggers; they act like they're always hungry when in fact they can fast for 5 days and still have the nutrients needed to live and be healthy. Once a day feedings are just fine, even every other day would be fine. One thing you can also tell her (and this is for your information as well), if you overfeed your fish can get constipated (aka swim bladder disorder), which isn't good. That is generally easy to fix, but some species are more prone than others. Your minnows should be fine, but fish like goldfish or discus and angels are more likely to have issues because of their slender figure.

The optimal numbers for your water quality are ammonia 0 ppm, nitrate
