I'm not sure what you could do now that they are actually here. They need to be in a tank of their own and be fed asap. What do they eat? they are probably too small to eat newly hatched brine shrimp, but will probably eat rotifers.
Here's an article on rotifers:

I'm sorry to say that you will probably not be able to set up your food source in time to rear your fry
But good luck in case you can
