I have 5 neon tetras in my tank, because 3 have died recently due to age. I would rather replace them with 3-4 cardinal tetras instead of neons. If I did, would they school together? And would they look nice even though they aren't the same fish? I think cardinals are nicer looking, so would they make the neons look more shabby?
I know that they probably won't school unless frightened, but I want them to be in a group so they are more comfortable.
