After hatching, I usually don't feed the newborns for 2-3 days (depending on how fast they are using up their eggsac). I kind of feel those days are my vacation days because after that, you have to be there all the time for them. The breeding tank is initially set up with floating plants that are rich in infusoria so when the babies are born, they have that as a first food source I use only use one drop of egg-bearing Liquifry before the hatching starts to feed the infusoria (all of my newborns never eat non-live food). On day 3-4, I start using vinegar eels twice daily. By the end of the week, I feed vinegar eels once a day and microworms once a day, and eventually stop the vinegar eels within a few days (replace that feeding with micros). Continue with the micros but also start feeding newly hatched (note, newly hatched which are when they are most nutritious) brines. I continue using both of those until the fish are big enough to eat grindals (stop using micros but continue with brines). After that, it's just a matter of matching their size to the food available--if they are big enough for frozen (defrosted of course) vitamin-enriched brine shrimp, glassworms, bloodworms. Usually they'll have develop enough teeth and jaw strength that they can bit off (rip off) these foods. since they are kids, they seem to always be hungry to I start crushing up pellets and start replacing one of their meals with the crushed pellets so they start getting used to dry food, which sometimes takes a long time to learn to eat.
