Big for a 20 gallon? 20 high or 20 long? If you say 20 long, why not just go for a 29? They have the same footprint.
Why would you want a big fish in a small tank? That is stupid. One fish alone is often stressful for the fish.
If you can do the 29, I'd suggest some fish from this category:
http://www.elmersaquarium.com/c106community5barbs.htm perhaps a total of 24" worth of fish, for example, six 2" Tiger barbs and three 3.5" Kribensis Cichlid for a total of 22.5".
If you must do a 20, perhaps about 16" of fish from this category:http://www.elmersaquarium.com/c106community2.htm

Catxcatxx is right, so many of those suggestions are just unthinkable for a 20 gallon tank. In spite of its initial appearance, 20 gallons isn't very big. Most of the fish that would fit your want are social fish and prefer to live with others of their own kind.
If you have your heart set on one big display fish, then you need a bigger tank. If a bigger tank is out of the question, you should reconsider what you want in it.
Good luck!

in case you do no longer choose genders that are over-dominant, you need to stay far flung from all livebearers; guppies, platies, mollies, swordtails. The adult males for all of those are very problematical on the girls, plenty so as that the girls choose a extreme huge type ratio whilst in comparison with the adult males or their wellbeing would go through. I recommend getting a school of 6 backside dwellers like Corydoras Catfish (6 of one species) and then 8 of a mid or larger living training fish. some super Catfish techniques are Albino Cories, Peppered Cories, Panda Cories, or Julii Cories. in case you may fairly have a non-catfish backside dweller you additionally can attempt 6 Kuhli Loaches. Any of those species extra healthful with each and all the mid/larger living fish i'm itemizing. some non violent larger/mid living fish are Dwarf Pencilfish, Flame Tetras, Glowlight Danios, Marbled Hatchetfish (whether they bounce with loud noises), Turquoise Danios, Neon or Cardinal Tetras, Harlequin Rasboras, Rummynose Tetras, or Zebra Danios. those are all non violent training fish that ought to be very happy in a collection of 8. in case you pick one species from each and each class, you would be nicely stocked. That sand isn't meant for freshwater tanks, it comes with creatures that stay in salt water and could fairly wreak havoc on a clean water aquarium.

there are a lot of really bad ideas recommended here.
anyway, fish that would be ok to be alone and grow to a size that would be ok in a 20 gallon are:
Banded Gourami
Gold Gourami (at a push - long tank only)
Paradise Fish
Spiketail Paradise Fish
Ceylonese Green Snakehead (but not if you're in the US- they're illegal!)
Purple-Spotted Gudgeon (at a push - long tank only)
Figure 8 Puffer (BRACKISH WATER ONLY)
and actually, after surfing around, i can't seem to find much else, outside of saltwater anyway. a community tank would be better off in that tank i think.

Akissing gourami would be great. My science teacher has a full grown one in a 15 gallon he seems to be healthy happy and friendly

This is what you do. You go to local fish stores in your area(not petco or petsmart or you will shoot yourself in 2 days)
Go to some chinese owned small fish store, trust me you will be happy and tell him gary sent you. lol. Buy a Red parrot( 2 big ones or 3 small ones) They will grow to a fair size in your 20 gallon tank and they arent hard to take care of. Now if you plan on sizing up your tank to lets say a 30 or a 50, buy a flower horn. They are intelligent and aggressive a deadly combination

I would put in a gold fish. It will grow larger depending on the amount of space it has to grow in. I have one larger than my hand (it is in a 55 gallon tank). Good Luck.
Have a great day!

A RED OSCAR BUT IT OR ANY OTHER WONT GET TOO BIG IN A 20 GAL TANK. OSCAR WILL GET REASONABLE AND IS CONSIDERED TO BE THE SECOND MOST INTELLIGENT FISH GOING NEXT TO ONE KNOWN AS THE AFRICAN ELEPHANT NOSE FISH. MY REDS (3) GOT PRETTY GOOD SIZED IN A 60 GAL TANK AND THEIR ANTICS ARE WORTH A MILLION BUCKS
