Most aquariums are suitable for bettas, they can live in 1 gallon aquariums but it would be better to keep them in 5 gallon aquariums or larger. In warmer climates bettas may not require a heater even during the cold winter months. Sometimes heaters are only required during winter. There are small aquarium heaters for 1 - 10 gallon tanks.
