Congrats!!
I don't feed my con fry at all, I just feed the parents as normal and leave the algae on the back of the tank and any decor it starts to grow on, the fry eat what the parents drop and graze on algae until they are big enough to feed flake or small pellets to.
So the question becomes what are you going to do with all the fry you grow out?
I know around here I could not pay the lfs to take them they just don't want them unless they are mature females that "look pretty".
For those who say eggs are bad for fish you are sadly mistaken. You CAN feed Hard boiled egg to fry for their first meal after they grow on the Infusoria. I have been doing it for years and all my fry from Managuense to Zebra Danio have grown strong and large. Fry can also eat the Infusoria that grow off Romaine lettuce and potatoe as well as any other vegatation which gives them their first meal. Remember the fry don't eat the actual vegatation just the little invertbrates that grow off them. I would recommend feeding whole eggs to an adult fish as it is alot of protein to digust and it makes a MESS! Then after the fry grow out a little more they can be fed flakefood or Hikari First bites but I just go straight to Brine shrimp that are fairly large as I get the fastest growth out of that.
