If you want your fry to survive you may need a breeders net to place them into so that the other fish in the tank don't eat them. You can feed them finely, crushed flake food that you are feeding the parents. Feed them about 3 times a day and keep the water/net clean as you can. They should grow for you. Don't overfeed too much. you don't want them living in dirty conditions.
Best of luck.
