I currently have one of my rainbowfish in a hospital tank, and I'm just worried about the oxygen level because it's a small (1/3 gallon) container that doesn't fit a filter or air stone.
Will the oxygen levels be okay if I change the water everyday? Or should I change it more often?

I agree. That's a very small tank, especially for a rainbow fish. Rainbow fish do best in highly oxygenated water. Hospital tank should be at least a 10 gallon in my opinion. What size tank was the fish in originally and what are you treating it for?

I don't really have any other options for a hospital tank. She was originally in a 20 gallon, I took her out because one of her fins is clamped so she can't swim well, I wanted to be able to keep her water spotless in hopes that it would help her.
Would it be better to leave her in the 20 gallon and just see how she does?

Yeah I would just leave her in the 20 gallon and do extra water changes

I agree with Jeaninel. you should have at least a 10gal tank on stand by, even a 10gal storage container with a CYCLED sponge filter is enough in a tight spot and unless the room is a constant temp you really should have a heater in a hospital tank, the fluctuating temp might stress the fish out more on top of the illness/injury.
