The Twin Tail Halfmoon Betta male is a stunning and elegant fish, admired for its large, symmetrical fins and double tail that forms a full 180° halfmoon spread. This variety thrives in warm, clean, and calm freshwater aquariums with minimal current and plenty of hiding spots from plants and decorations. Males are territorial and should be kept alone or with very peaceful, non-fin-nipping tankmates. A heater and gentle filter are essential for stability. Feed a high-protein diet of quality betta pellets, supplemented with frozen or live foods like bloodworms and brine shrimp to maintain vibrant colors and fin health. Regular water changes and careful monitoring of water parameters are key to preventing fin damage and stress.
