Before loading your tank you need to cycle it.* I highly advise you to not cycle with fish, as it is, in my opinion and many others', a cruel practice.
Here are some tips on fish for once your tank is cycled. (you might want to write these down, as old posts tend to get buried--that way you'll have them handy for when you get fish)
do TONS of research on fish, fish, fish!* read anything on them you can get your hands on!
do NOT listen to pet store workers, as they don't know anything about fish.* ask questions here where we have some experience with fish.
add your fish slowly!
test your tank a lot at first.
a 10-gal can hold 16.6 inches of fish (convert everything to cm if that's what you go by) (i'm assuming it's a standard, rectangular one)* so, you need to find out how many inches (or cm) the fish are that you want to get, and how many you are getting.
know a lot about the fish you are getting.* for example, if you are getting a fish that shoals, or swims in groups, you need to buy at least six.
here are some common, small, peaceful, and fairly hardy fish:* (* means most hardy/tolerant)
Cherry Barbs*
Zebra Danios*
Guppies
Platys*
Corydoras Catfish (many species)
female Bettas
Harlequin Rasboras*
Neon Tetras
Dwarf Gourami
these are just a few options to start you off.* as you learn more about fish, you will discover more and more options.* there is a lot you need to know to keep fish successfully.* don't get discouraged, but try not to make any mistakes by rushing to get fish before you know everything (not that you will or anything!).* read all of the articles for beginners on this site.* most of all, have fun!
by the way, how often do you plan to move your fish?* moving can be very stressful, and in fish stress can be a killer.
