Keep in mind that if the females you bought where kept in a tank with males at the fish store they could already be pregnant and may have fry even though there are no males present in the tank currently. Because they are live bearers the fry develop within the female until they are a certain size and then the females give live birth. They don't deposit eggs and "spawn" like egg laying fish.
Good point. Mots of them will die.
When you have just two fish of any kind, sometimes there tends to be more aggression then when they are in a group of 3 or more... If the larger female becomes too aggressive towards the other female, you might want to consider getting another female or two? That might "offset" the aggression that one fish can have towards just one fish... this would take some pressure off of the other fish in your tank.... Just make sure they are also FEMALES.
Do your Research on how to identify males from females!!! Unfortunately, most of the time, you can NOT rely on the sales staff in your LFS to identify the gender of fish. They are usually not trained and are usually inexperienced, so you have to rely on your own knowledge.

Ok, all wonderful advice, it's been a minute since I been back in the fish game.When you have just two fish of any kind, sometimes there tends to be more aggression then when they are in a group of 3 or more...
