On the one hand, you can say that the Hickey is a minimalist animal, they love the space. You don't need to fill an aquarium with lots of plants.
The aquarium for your Betta can be glass or acrylic. In addition, you can add live plants or plastic. Use gravel that absorbs waste and don't forget to heat it because Betta fish will want to stay warm. Get a betta food such as bloodworms or bloodworms. Consider water and fish treatments.
