If you want a single fish for a 20 gallon tank, a fancy goldfish would be a good choice. Fat bodied fancy goldfish only, not the longer bodied commons. If tropicals are more your speed, an Angel would be nice and would grow into a real show stopper. A single male Jack Dempsey would also be a nice showy fish for the tank.
If you are looking for a community tank, you need look no further than tetras. The majority of tetras sold in stores will be comfortable in a 20 gallon tank even at adult size. Add in a few cory catfish and a top water fish like a few male guppies and you're set with a colorful, active and easy to care for community tank.

high or long.
Which is your 20 gallon, as it plays a important role in how many fish, the longer tanks are better for more stocking as an increase in surface area. High tanks, you cant stock as much due to the lack of surface area.
The most common choices(would not be a goldfish) but try looking into barbs and tetras. Common, and colorful.
Certainly you can look into tiger barbs, cary catfish, neons, etc...

It depends on what you have and what you want to look at. Cichlids are very colorful and active, but they are aggressive. A community tank, neons, white clouds, platties, mollies, etc, is much easier to maintain, feed, and is cheaper to buy the fish. What are you in the mood for? A community tank allows for more fish while cichlids are VERY territorial. Hope this helps!!!

Very few people can resist a figure 8 puffer once they've seen them. Their expressive faces, and propeller like fins make them an interesting addition to a freshwater aquarium. Puffer fish derive their name from their ability to inflate themselves with water or air when startled (a defensive mechanism - it's harder to swallow a large fish than a small one).
Even when not startled, they have a rolly polly appearance. You can easily spot a well fed puffer by it's rounded belly. Puffers have two pairs of teeth, each of which are fused together giving it a beak-like appearance. This unusual arrangement of teeth gives it the ability to crush hard materials such as the shells of crustaceans.

i have a kind of overstocked 20 gallon with 1 betta, 2 pearl gouramis, 4 sunset honey grouramis, a school of rasboras and a bunch of ghost shrimp for clean up because the gouramis love to eat plants and make a lot of food for the shrimp.

Angel fish and gold fish are a hardy and easy to care for species. That is why they are both a "classic" choice for a 20gal tank.
