Hi T3ddy,
It's nice to hear some of them are already hatching .. heat has speeded up development, hence reducing the incubation period.
You can start with microworm .. gardneri are big enough to take it (green water would be too small for this sp.). Just start to think of upgrading the container to about one litre per fry now. Not too small cause of overcrowding .. not too big for the fry to find their food.
Congrats and well done.
