Will different cory species school together?
It doesn't matter if there are different types of cory's in a tank, it won't stop breeding, but some cory species are more open to cross breeding which IMO isn't desired.
If cross breeding happens it's usually between cory species that are similar in body shape, markings, and such. Your albino and emeralds can breed as they are the same species. They are brochis splendens which isn't a true cory but in the same family the same as aspidoras.
