Wanting to add a school of fish. What?

[joeyt66]

Looking at adding a school of fish.(not right away but later on ). What are some good fish that would look good in a 220 with the others in my sig.
I was thinking blue damsels as they are really bright blue and would look good with abot a dozen or more. Not really liking chromis (not as colorful as the damsel but less aggressive). Nor do i like the cardinal fish. Looking for something relativly cheaper (doesnt have to be )and bright coloured.
Any ideas????
