First...relax

Second wait to see if they are viable eggs and you get wrigglers. Once they hatch out the first couple of days they will live off their egg sacks. If the parents don't eat them before they become free swimmers you will need to get food for them when they are free swimming. I use crushed pellets or flake. You can crush them up into a powder and feed to the fry. I have a dropper that I use to target feed the fry so they can find the food easily.
The other major thing you will need to do is water changes. I try to change 30-50% daily with fry. So if you can siphon off the swimmers and get them into a smaller tank water changes will be more manageable.
Good luck!
