Male Betta fish are notoriously territorial, making them best suited for solo aquariums or with non-aggressive tank mates. Pairing them with peaceful freshwater shrimp or snails can work, but careful introductions are needed.

Optimal Environment for Betta Fish

Bettas require warm water temperatures ranging from 76°F to 82°F. Their tanks should also have a gentle filter to avoid stress from strong currents.

Feeding and Maintenance Practices

Provide Bettas with a balanced diet rich in protein to maintain their vibrant colors and overall health. Their tanks should be cleaned regularly, and water parameters must be monitored to keep them happy and thriving.
