They might school, I've seen it happen with different species schooling but they'd be happier in a species only school. I've never seen a Dwarf Albino Cory, but who knows, there might be one out there. Most Albino Corys are Corydoras Aeneas from what I've seen. Either way, you should get a few more Corys so they can have a school of at least 4/5.
