Hello! I got in an argument with my buddy today on whether or not different kinds of corys school together. I said that they are best with their own kind (like jullie with jullie or panda with panda) My buddy said that 1 jullie, 1 panda, and 2 albino corys would do just fine in a tank. I always thought that 4 or more of their own kind is best suited. My question is, which one of us is right? Are we both?
