I turned the remaining cory fry loose in the 55 gallon tank last week. I know there are at least 3 (probably more) because I can count that many out at one time in a tank with a lot of hiding places. I hope more than 3 made it. I didn't want to turn them loose so soon, but 3 had died in one day and I wondered if they were getting enough food, etc.
I also found a larger fry (bigger than any in the breeder net) but much smaller than fry from the spawning before last. My guess is that this was one that hatched on its own somewhere in the tank.
When these guys get bigger I am going to move 3 or 4 of the older ones into my 20 gallon. Here are some photos of the newest fry, the "mystery" fry and an older one from the previous spawn.
If I decide to try to hatch eggs again, I will move the newly hatched fry into my 10 gallon that isn't running right now and use a sponge filter.
