Fancy goldfish need a minimum tank size of 30g to grow up in but much bigger would be preferred. Comets or "plain" goldfish would need a bigger tank yet.
Maybe try an snail or some cherry shrimp for the 2g? IMHO it's too small for any fish I'm afraid.
It's good to see that you've decided to give your betta a better home. :)
