Rams need a very established tank, 3 months at least is recommended, especially for german blues. Swordtails aren't a good idea in your aquarium, they will need more space, and mollies aren't the best (but they are doable). I would stay away from CPDs in that size tank, with those other big fish. Do you know how to appropriately cycle a tank? Also, neons shouldn't be in a 5 gallon, you should add them to this tank. I'm thinking maybe:
- 6 neons
- 5 corys
- 6 danios
- 1 honey or dwarf gourami.
Edit: Oooooookay, just read the post about adding fish. Is the tank cycled? Or are you doing a fish in cycle? By the way I don't recommend rams to beginners.
