Is my aquarium ok for fish?

I have a 20w T5 light, 10 pounds super natural substrate, 6 Argentine swords, 5 pea ferns, 4 unknown plants(was in my 29 gallon show here http://www.youtube.com/watch?v=9_ayNvA19TY), 1 tetra whisper 5-10 gallon filter, no oxygen, no co2, and a 10 gallon tank. Any suggestions for fish that do ok with no air pump suppling oxygen. I think I'm gonna put a bleeding heart tetra from my 29g because he's getting picked on. Thanks a million!
