Though I have never tried them, I really like the look of a shoal of copper sweepers - they are about the same price as the cardinals. A caribbean fish too.

If color is what your looking for, I agree that anthias is your best be.
I've got groups of many if the fish suggested in this thread (chalk basslets, PJ cardinals, a few different types of anthias) and none of them schoal. My chalks did when I first put them in because they were small and felt threatened; but once they settled in and grew a bit, guess what .... No schoal anymore.
What about a group of Royal Gramma's? They'll act pretty similar to the Chalk Bass but are one of the prettiest fish in my eyes.
Agree on the blue eye/threadfin cardinals. I have 8 in a 120 and they hang together except for when one pair is clutching, then those 2 go to the opposite side of the rest. In my 60 i have 5 of them and they hang out together as well.
Firefish are working well for me too. 4 hang out together in a 60.
