Agree with this, he will probably eat them.
I picked up a mini food processor at a rummage sale, add a little tank water, a pellet or two, maybe a few peas, puree and shoot it into the school of free swimmers, after pureeing I sometimes add the newly hatched brine shrimp to the mix, helps the fry associate the puree with the live food..
Small frequent feedings are better than large amounts all at once.
If water quality gets bad from overfeeding, multiple fry die offs are common
