There are also some nicely colored mollys (check out the mollys at petsolutions.com). I have a pair of yellow/gold Cremecicle mollys (had 3 but one passed away leaving a very gregarious male with one PG female who's about tired of his amorous intentions!). I also have some black Dalmation lyretail mollys - but the Red Dalmation is a beauty who I will eventually add to the tank. But the advice about 2 to 3 females per male... TRUE! My threesome of Cremecicles were fine till female #1 died, then poor female #2 has gotten WAY more attention than she wants. But all said, the mollys are a really fun fish, peaceful, showy, and have loads of babies (livebearers of course). You'll find the right ones... just like I'm still looking for the next tank with some "mild mannered", colorful, breeders in the cichlid category (and of course more tank mates). Good luck!
