My understanding was that as long as the angels don't get big enough to fit a neon or cardinal in its mouth, the tetra won't get eaten. Neons are smaller than cardinals, so maybe this is less of a problem with cardinals...

I would just buy the angels small. That's what I did and I had no problems. It's pretty awesome to see them grow too.

My sister has a 200 gallon tank she keeps a school of 30 cardinal tetras with discus and clown loaches she has had this set up for about 6 years they all seem to get along nice the tetras die off since they don't live that long and she just adds some new ones once in a while I myself like the cardinal tetras

Am pleased that your sister has provided suitable size tank for the Discus/clownloaches.
Cardinal tetra's can live to four or five year's in captivity, which is considerably longer than in the wild where other larger fish prey on these easy to spot fish.
Could be they aren't living long in Discus tank for most basic reason.

The demise of the cardinals may be due to the hardness (GH). When kept in very soft water having a GH of 4-5 dGH, they will live for more than 10 years. But as the GH increases, their lifespan shortens. They die from calcium blockage of the kidneys primarily, due to the calcium in the water. This has beeen determined by dissection of dead fish in a study some years ago. The higher the GH, the shorter the lifespan. They look and behave normally up to the point at which this occurs.

I suspect this occurs with many other soft water fish as well. When fish just die for no obvious external reason it may well be due to internal issues caused by inappropriate water parameters.

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.
