I just got a new 20 gallon tank, and I was wondering what I could put in there. I live in the US, so you know.
 
You could puts lots of things in there, from tetras and rasboras to small puffers and catfish. Not all at once, mind.

Without knowing what you like/want, we can't really say. We could give you a list of the hundreds of species suitable but that wouldn't help much.
 
do you think 2 mini red swordfish (Boy and Girl) will be ok
 
Its best to have 2 females to every male. If you want swords i would go for something like
3 swords
10 shoaling fish like some sort of tetra, rasbora or small barb
trio of apistogramma (1male 2 females) My profile pic is of my male Apistogramma Agassizii
6 corys or 1 plec like a bn or clown plec.
 
I made the mistake of stocking what I wanted before my tank water settled in, and my lower than expected pH level killed off 5 guppies. It might be good to test your tap water, and/or cycled tank water, and then once you know the general pH range, you can make a more informed stocking decision.
 
As GvilleGuy said get a test kit and find out what your water parameters/conditions are like. If you have hard water with a pH above 7.5 than a live-bearer tank could be in your future which fits your plan to have red swordtails. Just keep in mind the 2/3 females per male ratio.
 
And if your pH is in the 6.0 to 6.5 range, a tetra tank might be in your future!
 
Read the post from Waterdrop from today (Aug 15th) in this thread - I think it applies well to this discussion:

A more important piece of information for a first time fish tank owner is to get his head around cycling the tank. That is a process you should start right away before even worrying about what fish to get. That way, when you have everything figured out, you will only have to wait a shorter time before adding in your first fish. There is a link to fishless cycling and to fish-in cycling in my signature area. Once you have read through the information there, you will probably have lots of questions on how to go about doing your own cycle. Please feel free to come back and ask for advice on that subject, it can be a bit hard to really grasp at first.
As far as selecting fish, I find it is often a question of tastes when it comes to a stocking plan. I would suggest that you wander the aisles of your local fish shop and keep in mind that many of the fish on display grow much larger than they look in the store. Just write down things that appeal to you and that are small enough for your new tank. We can help you put together a stocking list from the fish that you like. Be aware that different fish require different waters so depending on how hard your water is, we may suggest an alternative that looks somewhat like the ones that you liked has a similar appearance.
