How much was the zebra plec? if it was under $100 chances are either it isn't a real zebra plec (there are many plecs that very closely resemble it) or there is a reason it's cheap (e.g. dieing). The rasboras are good, as are neons/cardinals. Barbs are pretty good, but I haven't had any experience with them. Some other fish you might try:
Congo Tetra - bigger schooling fish, beautiful white irridencent
Penguin Fish - another schooler, nice effect in mass
Cories - there are dozens of different breeds of these, look a little like the loachs but more peaceful smaller and work best in schools (minimum 3 of the same species)
Rainbow fish - stunning color, little on the expensive side, various species
good luck!
