Changing stock, Cory question

[Dreamwallaby]

So I have been playing around on aqadvisor. I know from a previous post I need to rehome the Chinese algae eater. Aqadvisor also suggested I remove the spotted Raphael cat because he could get too big (only 2 inches right now). If I do that the. I want to add 2 panda and 2 albino Cory. Aqadvisor says I need 4 of each. Won't they school together or do I need that many because of their color?

Usually all cories will school together. But I've found that you'll usually find the same kind hanging around together the most. I would suggest four of the same species rather than two of two species. But it doesn't really matter all that much. They do love the extra company though.

Cory's are shoaling fish and prefer to forage in groups of their own species. They will go around with other cory's but seeing a group of the same species of cory's interacting as they would in nature is worth it.
