Betta fish, or Siamese fighting fish, are colorful and territorial freshwater fish from Southeast Asia. They thrive in warm water (76-82°F) and prefer tanks of at least 5 gallons. Bettas are carnivorous and need a diet of high-quality pellets and occasional live foods. Males are aggressive toward each other, while females can live together in groups. With proper care, they typically live 3 to 5 years.
