I've got gazillions of those little things, my mummies and daddies keep making babies!
Microworms and BBS are great food, as well as sinking flakes when they start getting a bit bigger. They also do great on decaps BS, and zucchini. You don't need to feed them for about 3 days until they absorb their yolk sac. Keep the water nice and clean and aerated. Don't stress if some of them die, once they're a month old though, they're pretty hardy and can live in pretty much the same conditions as the parents.
Good luck, they're awesome to watch grow!!!
