The Halfmoon Twin Lobe Betta is a showstopper in any freshwater setup. With a dramatic 180° tail spread that forms a near-perfect half-moon shape and a rare twin-lobe (double tail) mutation, this Betta combines elegance with exotic appeal. Males display bold, flowing fins and intense coloration ranging from deep blues and reds to pastel iridescents—perfect for centerpiece tanks or Betta displays.

Fun Facts:

• The “twin lobe” or double tail is a rare genetic variation that gives the caudal fin a symmetrical split, often making the fish appear larger and more ornate.

• Bettas are labyrinth fish, meaning they can breathe atmospheric air thanks to a special organ—so they don’t require aeration like other species.

• These Bettas are intelligent and can recognize their owner, follow your finger, and even learn simple tricks!

Diet:
Carnivorous – thrives on high-protein diets such as Betta pellets, freeze-dried bloodworms, daphnia, and brine shrimp. Occasional frozen foods help boost coloration and vitality.

Compatibility:
Best kept solo or with peaceful, non-fin-nipping tankmates (e.g., small rasboras, snails, or corydoras). Avoid keeping with other male Bettas or species with long fins.

Perfect For:
Aquarists looking to showcase a unique, vibrant fish with personality and flair. The Halfmoon Twin Lobe Betta adds movement, beauty, and intelligence to nano and desktop aquariums alike.
