In most cases Cories wont eat fry, but they might like to snack on eggs.
I don't have any 'personal' experiences with them, but I do know a bit. They are pretty easy to keep and are one of the smallest Cories out there. They like to be in groups of six+. They like to be kept in even bigger shoals then other Cories. They will eat most food given. A good temp range is between 22-26C as with most Cories. They're not that picky about their pH, but between 6.8 to 7.2 is best.
I soooo want to get these cute little buggers I saw them at a store close to Berkeley Ca, and I should have gotten some cause they are so cute and small. I hope that you have fun with them, by any chance are you from the Bay area? since I want to find more places that carry them.
I have peppered corys and they seem to like to snack on their own eggs when they are layed, however when I see that the eggs are layed (if I want to) I gather them up and spare them from getting eaten by their parents or other hungry fish (ghost shrimp!, dwarf puffers).
