my environmental science teacher said 2 gallons is big enough for a betta fish, what do you think?

It can be done, so long as you can filter it and keep it at proper temps. But just because something can be done, doesn’t mean it should be. Keeping a betta in a larger tank is so much more rewarding, plus you can have a much neater looking tank if it’s large enough to decorate. Happy fish, happy person.

Sure, you can keep the fish alive, but it’s like keeping a dog in your backyard on a chain all its life. It can be kept physically healthy, but it’s not going to be happy, and it’s not much fun to interact with.
