As previous posts have indicated (correctly), corys will shoal together as individual species or mixed species. I try to have three of each species (when I can get them or can afford them), and I currently have 2-3 of several species in my two aquaria. My experience has been that when given the option (to shoal with their own species or other species) they usually prefer their own species, but will now and then mix in with the other species in the tank. Your plan of 4 of each species is fine. Interestingly, I have found over the years that C. panda are particularly fond of remaining together, moreso than the others I have kept. I currently have three C. panda in my 70g, with three C. similis and 1 C. duplicareus (bought the last one in the store and haven't seen any since). The pandas frequently chum around with the duplicareus, but much less often with the similis, and they (similis) tend to remain alone or with one or both of their species.
