I must with respect not agree with adding any fish to "scare" other fish in an aquarium. I understand your thinking, but if the cardinals or any other fish are affected by other fish in the tank to the point that they remain grouped more than they otherwise would, this is absolutely due to stress. And stress weakens any fish, causing health problems that the fish would otherwise be able to fend off, and a shorter lifespan. [This may be the issue in the other post with discus/cardinals.]
And while it is perfectly true that such fish may occur together in their natural habitat, that is a very different world from the artificial space we create in even the largest home aquarium. Fish in nature have the ability to move away from danger if they feel threatened. This opportunity does not exist in an aquarium, so the stress on the fish is considerable.
And angelfish are predatory, more than discus, and should never be combined with linear small fish (cardinals, neons, glowlights, etc). The disk-shaped tetra usually work well, provided the fin nipper species are left out.
