I used frozen and top grade pellets for conditioning.. for live foods for the babies are basically cultures.. micro cultures. They stink, but are small enough for the babies to eat (they won't eat processed fry food.. needs to be moving). The cultures will be ready to feed whenever you want.. you just have to collect the food. The BBS will depend on the temp of the hatchery.. but usually it's roughly a day to hatch, so start them early in the morning so you have food available throughout the next day, etc.
This is against rules, but it has some good info. On the right is the list of links to the different types of first foods and how to care for them. If the link is removed, let me know and I'll send it via another way.
