Is it possible for a betta fish to live in a 1.5 gallon tank?

While a betta fish can technically survive in a 1.5 gallon tank, it is not an ideal environment for their well-being. Betta fish require at least 5 gallons of water to thrive, as smaller tanks can lead to poor water quality and limited swimming space. It is recommended to provide a larger tank with proper filtration and maintenance for the betta fish's health and happiness.
