I keep a 12 inch aimara with cardinal tetras with no issues. But he'll attack everything the looks like a potential threat and eats pretty much everything else. It seems like a cards are small and fast enough that it's not worth the trouble.
I am going to assume one of these days that flag tail is going to be chomped in half though.But you never know!
Good luck!
