there are a lot of options....a betta sorority, a 4-way divided male betta tank, a community tank (livebearers are great for that), two or three goldfish but be warned they'll outgrow it! a school of guppies if you know someone who will buy or adopt a large number of babies. hell, you could even build up one side with a slope of substrate and make it a fish/amphibian or fish/reptile environment. the possibilities are endless!

So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth,
And pray that there's intelligent life somewhere up in space,
'Cause there's bugger-all down here on Earth.

Well... You can have a female betta sorority of 3-5-7 Fish... Or a 4-Way divided betta tank for 4 male bettas (5 Gallons Each)... You can have 2 or 3 female Oscars Or 1 Male Oscar... You can have gold fish... Rainbow Shark :D You can really put any fish there... pick any that catch your eye!

Tail fins and dorsal fins,Spread, expand, as well as sail,When flying in full mass,They captivate like nightingales,Attempting to breed baby fry,Their actions may surprise,For how betta fish procreate,Differs from routine rise...

You can't have Oscars there. They need at least 75 gallons, let alone 20. Neither Goldfish or Rainbow Sharks. Please don't spread around wrong info. Sorority, Guppies, Mollies, Divided, Dwarf Puffers, etc.

Over hundreds of bettas die in their small, dirty cups each day. Only you can help them live. Research and then save them, today!

A trio of Honey Gouramis, pygmy cories, and another species of dwarf pencilfish. At least this is what I'm looking at.

It depends on your local water parameters. These are things such as hardness and pH from your tap water. Not all fish can live in all types of water. They have specific needs when it comes to things like that. Goldfish and livebearers are hard water fish; they need water with a high mineral content to thrive. Most tetra and gourami are soft water fish; living in hard water will decrease their life span as well as make them less colorful. So once you tell us how hard your water is, we'll be able to make some good suggestions.

Small strains of Gouramis are very pretty and can live in smaller tanks, Rainbowfish are cool and if i remember correctly can live in smaller tanks. Galaxy Rasboras are colorful schooling fish that would do well in your tank, i love having guppies, just get a couple different colored ones (2-3 females per male) and just wait! soon you'll have a ton of different colored fish.
However as thekoimaiden said, what fish you get depends almost entirely on the parameters of your water, but also how much money you are willing to spend, whether you want a freshwater or saltwater tank, if you have a heater, and for certain types of fish how fast the water current is moving.

happy owner of a wild type GFP axolotl named Percival and too many guppies to count.
