1 beta or 1 dwarf gourami would be your best bet. You could put in two 1 inch fish, but there aren't many fish that small that are happy in groups smaller than 6.

The formulae is 1cm per litre of water for cold water or marine fish and 1-2 cms for tropical. A 2.5 gallon(12 litre) tank is very small so you shouldn't keep more than twelve cms. About 4 tetras would be all! Gold-fish are not a good choice as believe it or not they are really big fish (if allowed to grow as they should)! Have you thought about frogs instead. In that tank you could keep a pair of African Dwarf frogs! They are entertaining pets and have similar requirements to fish. You just need to make sure the tank is covered!

Although the 'rule' is 1" per gallon, you also have to take into account how much space the fish have to live in in general. This tank is too small for most fish, and you best bet is to provide a nice home for a betta rather then a lousy home for fish that just aren't suitable for them.

Answers based upon length of the fish such as 1":1gal. are misleading because the metabolic demands of the fish is more closely proportional to its mass than its length. Consider that when a fish doubles in length, its mass increases by 8X (Similar to the formula for calculating the volume of a circle 4/3pi*r^3.
A typical tank of that size can sustain about 8 grams of fish with no worries.
The other variable is how well the tank is filtering its water and/or how frequently is the water being changed. A fish has a metabolic demand for a flow of water of about 0.16 liters per kilo per minute and a demand for oxygen of 2ppm per kilo per minute.

You can put in one 2.5 gallon fish

I cannot remember the formulae, but it actually goes on the surface area, and is different for cold water and warm water fishes. It will tell you the total length of fish allowed, so you can also have more small fish, than if you had large fish.
You can have more warm water fish, because warm water absorbs more oxygen.
Try an aquarium set up book for the formulae.

I have a large tank and was told never to put in more fish than that if you lined them up they would be longer than the tank hope that helps

1 beta fish. Maybe 3 guppies, but only if you have a heater and good filter set up. Your best bet is probably the beta.

I suggest you buy a tank divider, divide the tank's volume equally and put one betta in each side of the tank.
