no goldfish, the get between 6" and 24" depending on the type, and there is no such thing as a "small koi" they all get huge...
anyway, your tank is two small to keep anything besides a betta really... I suggest checking out a hexagon 5gallon which take up about the same amount of space but increase your options.
if you get the 5g you can chose a school of 4 of one type of tetra or danio (check out your pet store, there are neat varieties and now even glofish NOT to be mistaken with golDfish) and 2-3 of a smaller type of cory cat.
here is an example of a small hex tank:

Goldfish will get to be 5-18 inches as adults, and will outgrow a 2 gallon tank within a few months. Koi are an even worse choice as these can reach 3 feet.
Bettas are lively if they're kept properly - a heater is necessary because they're tropical fish and need a water temperature of 76-86o. A gently filter is also a good idea, despite what people think, and they can help keep the tank cleaner. I keep my bettas in 2.5 gallon or 5 gallon tanks with heater, filter, driftwood, and a few live or silk plants and they never seem to stop exploring.
Some other choices if you want a fish that can do well in a 2 gallon would be a small group of male guppies (more colorful and no reproduction), Endler's livebearers (a relative of the guppies), one dwarf puffer (although a 5 gallon tank would be better and the tank should be cycled first), a pair of cherry barbs, or a platy. A dwarf cory might work, but these are bottom fish, so they won't make much use of the height of the tank.
You also aren't limited to fish. Consider getting a mystery snail (just one!) or some freshwater shrimp. Ghost shrimp are found in most pet stores as feeder (cheap, I can get these for around 5/$1.00) or you can go with something more colorful, like cherry red or crystal red shrimp: http://www.petshrimp.com/shrimpspecies.html

There is not much that can be housed comfortably in a 2 gallon tank. I would suggest maybe some ghost shrimp, a few guppies, and/or on aquatic frog. Kids especially love the frogs, and they are more interesting than some fish.
The problem with having such a small tank is that it will fill up with ammonia very quickly. So you will need to do water changes at least once a week, and stick to no more than three small (one inch or less) fish. You can get free care guides at some pet stores about basic tank care/setup and how cycling works.
Don't forget to dechlorinate your tap water before putting it in, and letting your tank run for at LEAST 24 hours before adding any fish. (This allows beneficial bacteria a little time to grow before your fish are added. This bacteria turns ammonia into nitrates which is less toxic. This process will happen eventually regardless but you should always let it happen before fish are added.)

Your best bet is going to be the betta. I would go with only one fish becase the size of the tank.
You need to keep in mind you'll need to change water 2 times a week and feed it a good betta pellet food and make sure you dont over feed it as this would cause water problem that would end in the death of the fish.
Stay away from gold fish there to messy and they just dont work in small tanks.

not a whole lot of choices with a 2 gallon tank. goldfish are easy to take care of and will only grow as large as their tank allows (not 15 inches in a 2 gallon tank!) they're more entertaining than bettas, or at least mine are. you could also get a couple of neon tetras in that size tank as long as you had a little heater or light to keep the water "tropical" temperature. they lack personality and the cute factor but they are usually very active fish. i'd upgrade to a larger tank so you could have some fun fish.

I know bettas might seem a bit dull, but mine has tons of personality (especially since I got him a heater). He is VERY active and healthy. I keep him at the office - he swims to the front of his tank to "greet" me in the mornings, and seems to show off for my coworkers when they come to my desk. My 2.5 gallon tank is super low maintenance (I do water/filter changes when I need a little break).
Just a thought - a friend of mine raises brine shrimp (sea monkeys) to feed live to her desk betta. I've watched her do it - it's definitely not dull!

I advise getting a Betta fish. each and every of the fish will want is a bowl or tank with a minimum volume of a million gallon of area. you're able to place a million or 2 pretend vegetation for hiding areas so the Betta won't sense under pressure. regardless of the reality that in case you get a a million gallon tank, you do no longer decide to overcrowd the tank by using fact the Betta will want a number of of room to swim around in. I hear Bettas can stay as much as two according to threat 3 weeks devoid of nutrition, yet because you're interior the place of work on Monday-Friday you're able to feed it as quickly as an afternoon conventional. Feed it as lots it may consume in a single set and then get rid of any extra nutrition. you'll want a small filter out and a heater. No air pump is needed by using fact the Betta will arise for air. I advise getting one that is obtainable in a small container from walmart, petsmart, or places like that because you would be doing that fish a great choose. they're going to be "saved" because you're putting them in a much greater spacial place. EDIT: one greater ingredient: they might stay off freeze-dried blood worms. that's what I advise for nutrition possibilities. 2d EDIT: final ingredient: you'll want a nicely suited to hide in spite of you positioned your Betta in by using fact Bettas are huge-unfold for leaping out of their residing factors. make certain which you do supply a nicely suited with air holes so as that they might breathe.

Try killifish. Get one male and 2-3 females. They will be very active, the male chasing the females all over the tank. And colors on many are phenomenal.

Go to a local fish store and see what they have that stays tiny when full grown, since 2 gallons isn't big enough for most other fish.

I believe you should go with two male Guppies or a Panda Moor Gold Fish. These fish will stick out and will keep you office live. I have a Siamese Fighting Fish in a 2 gallon tank now and to me it doesn't stick out more then my other fish.
