Cories that are the same species will tend to shoal together fairly well and will interact with each other much of the time. Albino cories are not a separate species, they are usually aeneas or peppers. Cories that are truly different species, will not interact as much as the ones of the same species but they will live together just fine with no problems. On some occasions, when a single cory has none of its own species in the tank, they will try to become a part of the group in the tank but it is not quite the same.
