Great News !!!!! First of all I would like to know if you have any other fish in the same tank?. If yes, then the chance of survival is quite "slim", as they finish off as food for the others. If you can, move the filter to another tank or else leave everything as it is & within a few days, move the pair to another tank on their own. Don't worry, they'll breed again very soon. 
Microworms are quite good to fry & you have to start feeding them as soon as you'll see them free swimming. Don't feed them before, as it will pollute the water. After a few days, try feeding them Live Brineshrimp & don't forget to make some "small" daily water changes.
If you need any other help, just post here & we'll help you. 
Please treat Corydoras as community inhabitants & not as scavengers.
