fish for beginner

[alessia55]

I have an empty 10gal fish tank in my garage at home that I want to take to my apartment and put fish inside. Besides gravel and plants, what else do I need? a filter? what kind? light? what kind of fish can I get? how many? can I combine different types of fish? I've heard a 1 fish per gallon rule, not sure if it's true. This would be a fresh water tank. Preferably some hardier kind of fish that don't need lots of special care. Thanks
