i think you should get rainbow fish too, and if you cant find that specific kind there are many other types of rainbows out there. these are my
other suggestions: CHERRY BARBS(i have them and they are great), ODESSA BARBS, GREEN TIGER BARBS, WHITE CLOUDS(as long as the barbs dont hurt them), RASBORAS, SILVER SHARKS, Red Tailed Shark
(not sure if they would get along), RUMMY NOSE TETRAS(i know you said no tetras but i just love rummy noses), Silver Dollar
(i dont know much about them so i dont know if they would be good with barbs or not), RAMS, PLATIES, ?MOLLIES?, CLOWN, SKUNK, OR ZEBRA LOACHES, BLUE, PEARL, CHOCOLATE, OR DWARF GOURAMIS.
if you need some info on these or other fish you can use this website.the chrt can also give you more ideas for fish. :D http://www.fishpage.info/behavior/55...Leporinus.html
