I would see that the tank is cycled before adding any fishes and as already mentioned,,your water from tap (pH ,hardness or lack thereof) will determine which fishes are suited for your tank.
Guppies,mollys,Platy's,swordtails, all need hard alkaline water to do well in the long term,pH 7.5 to 8.0 12 to 15 dgh.
Mollies and guppies prefer warmer water 78 to 80 degrees F than Platy's and swordtails 72 to 76 degrees F.
Swordtail's and Barbs need lot's of swimming room and would do better in longer tanks than hex tanks In my expieriences with them.
