Your welcome :)
You could do a school of neons, though theres still the chance of nipping and picking on from both parties. Its up to you if you want to try it out or not, but whatever other tank-mates you choose, add them before adding your girls to limit aggression from them.
Personally, I have only kept Harlequin Rasbora with my females, no issues. I don't know how much they cost, but they're pretty neat little fish.
I'm afraid I have no personal experience with plants, so I can't help you there....I have a terrible green thumb. I do know that Java moss, Java fern, wisteria, swords, and anubis are pretty easy to care for though and I think all of those are low-light plants....
There was this website I'd found a while back that had a profile of al sorts of aquarium plants....I'll see if I can find it....
Ha! Here we go.... http://www.aquahobby.com/e_aquarium_plants.php
Hopefully that helps :)
