Chromis will school in large numbers if the tank is large enough. Only problem with that is they start to kill the weaker of the pack and sooner or later you'll only be left with 1 or 2.
Fish school to avoid predation, remove the predators and they stop the behaivor.
What you're really looking for is sociable fish... not really a school of the. Chromis are good, and cardinals are ok together. None of them are really schooling.

agree with andrew, i have 10 green chromis, i introduce them at the same time, then start at day3, they start to attack the weaker, one down one to go, now only 3 of them survive, and the habbit attack the weaker stopped. i also have 7 yellowtail chromis on the same tank, they have the same habbit. now only left 4 of it.
