Plastic plants, fine gravel, and a couple of small fish. Try neon tetras, guppies or zebra danios.

That tank is far too small to keep anything other than a single betta in. Most tropical fish are community fish (need to be kept in schools, usually consisting of at least four fish) - as such, there's no way you can safely keep four fish in that tiny tank. The tank is just too small to cycle properly, and your ammonia levels will quickly get out of hand, possibly becoming lethal.
Goldfish need a minimum of 20 gallons per initial fish, 10 gallons for each additional fish.
Just remove the air pump (if possible) and add a heater - you'll have an almost perfect environment for a betta. Ideally, no fish belongs in anything less than a 5-gallon tank, though, so if you could go a step up, that'd be best.
EDIT: Unless your room temperature is constantly at 76 degrees with no fluctuations in the temperature, you're going to need a heater. Bettas are tropical fish and do best at 78-80 degrees. Anything less, and you're looking at health issues (lower temperatures cause the fish to stress, stress causes the immune system to lower, lower immune system means he'll be more prone to diseases - ich is especially prone in unheated tanks).

I recommend a single Betta, Crown Tails are very beautiful in color. This fish does well is small habitat, such as your 2.5 gallon. And are very low maintenance.
I don't recommend getting tetras or guppy's because these are community fish and do well in groups (3-5 fish in tank).
A good rule of thumb is a full grown inch of fish per gallon. Good-Luck!!

A Betta would be perfect! I have tried to keep a single feeder goldfish in a tank that size.. and the little thing died :( But the Betta was perfectly happy! Best of luck!

A betta would be great in this environment with a filter. You don't need a heater or air pump for a betta either.

A few guppies or Mollies. But a beta would be a waste to put in a 2.5 gallon when you can just keep them in a cup of water. Tetras would be a good one, but they don't have such a great life length. Killifish are nice.

Plants and no more than a couple of fish. Most experts recommend a 10 gallon tank for any serious beginner.

I would recommend 6 small rosy barbs or zebra daniios, 2 cory catfish for the cleaning and maybe one small betta.
