1st: Flake food five times a week + Live food (Bloodworms, Tubifex, Brine Shrimp etc) about twice a week
2nd: You could use a plastic Syringe or a Turley baster and release the food near the fry
3rd: The fry should fine with the parents for a week or so (although the parents can and may begin eating them soon after they hatch, it depends on the parents some are great other are not). Do you have a spare tank for the fry?
