Hi there, this isn't really an emergency section sort of thread but rather a livebearer section thing- but, anways...
Livebearers(like mollys and guppys) are sociable fish and appreiciate having their own species around, personally i would not have a molly in a 14gal as they can grow anything between 3 and 4inchs long, and a group of them would be a bit crampt in there- personally i would swap the molly for 4 platys(3female and 1male) and get another 2 female guppys.
You need to stock the tank gradually otherwise you may face water quality issues, so i would only get either the platys or the guppys for now. As for future planning though, what sort of fish are interested in and how long has the tank been set up? What is your average tank cleaning/maintanence regime i.e water changes and stuff?
