How big is the tank? You can mix different species of cories, but you want to have atleast 4-5 of each species, given enough room.

If your tank is atleast 20g, then I suggest getting 1 or 2 more Albino cories and then getting atleast 4 of a second species. Different species of cories will hang out together, but don't really school/shoal IME. Even some that look really similar tend to hang out with their own kind. I have 3 different species of cories in my 55g planted and the individual species group together the majority of the time.

If you are only looking to add a few more, then I suggest just getting more Albinos, but if you have the room, you could definitely get more Albinos and another species. Just make sure you have the minimum group size which IMO is 4-5.
