Bboesmani Rainbows. you'll be hard pressed to find anything more colorful active, tough and peaceful. When I get some for my 55, the stocking willl be done.
If you want color, peacefulness and action, there are only three real options for freshwater.
1) Peacock cichlids from Lake Malawi (If you are not scared of Hybrids, you can get generic cheap, and with a sane m/f ratio, you will have minimal aggression.)
2)Livebearers (mollies, swordtails, guppies)
3)Rainbows
Others will argue, but where else are you going to get bright red, blue, green, purple, etc., with fish that don't constantly want to rip each other to shreds?
