try pygmaeus or habrosus corys, they are the dwarf species that are good in with apisto fry. But you have to wait until the apisto fry are big enough ( like 4 weeks old or older ) that they cant be eaten by the corys. Newborn apisto fry are small enough to be attacked by the corys if they are hungry enough.
