Well assuming you want to actually raise the fry, you need to somehow get them away from the rest of the fish in the tank, being that they will more than likely be eaten. Also, they will get sucked up into the filter. Your only real options is to put them in another tank (Better choice), or to put them in a breeding net you can buy at the pet store (Not as good of an option).
If you don't want the parents to eat them separate them either with a net in the same tank, or give them their own little tank. ALso feed them finely crushed flakes or baby brine shrimp. Also be sure to keep their temperature consistent and around 79. Also up to 3 water changes a week are good because this encourages them to grow.
