Just to be clear, and hopefully not redundant or annoying, ammonia, nitrIte and nitrAte are all harmful to fish in varying degrees.
I've learned that there are 3 ways to keep a betta:
1. keep him in a very small tank and change the water often enough that he doesn't get sick and die of ammonia or nitrIte poisoning.
2. keep him in a larger tank and cycle it with him in there, using his waste as the ammonia source, but risking harming your betta
3. do a fishless cycle in a larger tank and add your betta when the tank is cycled and there is no ammonia or nitrItes anymore.
Because I didn't know enough when I got my betta, I did option 2. If I could do it over, I'd pick option 3. I also learned that while bettas can survive in a very small tank, they don't thrive and they are much happier with more room. A large tank also gives you options of more fish, aquascaping and the like.
Don't hesitate to ask any questions. If you like, go through the "getting started" thread to learn more. You can also post questions there about setting up a new tank and cycling.
