Male bettas are renowned for their vibrant colors and expansive fins. These solitary and territorial fish often exhibit aggressive behavior towards other males or females, which is why they are usually kept alone. Male bettas can coexist with other fish species, provided they don't resemble bettas or have long fins. They construct bubble nests for potential offspring, demonstrating their natural breeding instincts. With proper care, including a minimum 5-gallon tank, stable water conditions, and a diet of quality betta pellets and frozen or live food, they can live for 2-4 years. The distinctive appearance and behaviors of male bettas make them attractive pets for aquarists. For their well-being, it's crucial to maintain the correct water parameters: Temperature should be between 75°-82°F (23.8°-27.7°C), Ammonia and Nitrite at 0 ppm, Nitrate less than 20 ppm, General Hardness (GH) at 3-4 dGH (50-66.7 ppm), Carbonate Hardness (KH) at 3-5 dKH (53.6-89.4 ppm), and pH between 6.5-7.5.
