Avoid goldfish. They will dirty your water quickly.

Guppies work well and can provide some nice color. I had a Betta in mine and two small albino catfish and they did well together.

Actually this is the best advice. Be careful with Betta though, they all have very different personalities. You'd need one that is very mellow. Additionally, Dwarf Guoramis would do nicely. They're very similar to the betta in that they have an organ allowing them to breathe air as well as using their gills.

Also, check out this website to make sure you're not overloading your tank:AqAdvisor - Intelligent Freshwater Tropical Fish Aquarium Stocking Calculator and Aquarium Tank/Filter Advisor

It might also be necessary to check into cycling your tank before you get started, or at least by a nitrite/nitrate/ammonia testing kit.
