Description
The Halfmoon Betta (Betta splendens) is one of the most popular and visually striking varieties of Betta fish, known for its unique, dramatic tail shape. These fish are particularly admired for their gorgeous coloration and the breathtaking appearance of their tail, which flares out into a perfect 180-degree arc, resembling a half-moon. Native to Southeast Asia, Bettas are known for their territorial and sometimes aggressive behavior, especially among males. Despite their aggressive tendencies, the Halfmoon Betta’s vibrant colors and graceful swimming make it a favorite for both beginner and experienced aquarists alike.
Key Features
- Scientific Name: Betta splendens
- Common Name: Halfmoon Betta
- Size: Typically 2.5 to 3 inches (6.5 to 7.5 cm)
- Temperament: Semi-aggressive, especially toward other males of the same species
- Lifespan: 3-5 years with proper care

- Appearance: Halfmoon Bettas are characterized by their large, vibrant tails that flare to a perfect 180-degree angle, with colorful bodies in shades of red, blue, green, purple, and even metallic tones.
- Tank Level: Surface swimmer, often near the top of the tank
Tank Requirements
- Tank Size: Minimum 5 gallons for a single Betta, but larger tanks (10+ gallons) are ideal for promoting better health and more swimming space
- Water Temperature: 76°F to 82°F (24°C to 28°C)
- pH Range: 6.5 to 7.5
- Water Hardness: 5-15 dGH
- Substrate: Fine gravel, sand, or a soft substrate to prevent fin damage
- Tank Setup: Bettas do well in tanks with plenty of hiding spaces, soft plants, and gentle filtration. Avoid strong water currents, as Betta fish prefer calm waters. Live plants like Java Moss, Anubias, and floating plants will provide hiding spots and add to the aesthetic of the tank.
Care Tips
- Water Quality: Halfmoon Bettas are fairly hardy, but they require stable water conditions. Frequent water changes (20-30% weekly) and a good filtration system are essential for their health.
- Aggression: Male Halfmoon Bettas should not be kept together, as they are highly territorial and will fight if housed in the same tank. Females can be kept together in a sorority with careful planning and enough space.
- Diet: To keep your Halfmoon Betta healthy, provide a varied diet. While Betta pellets are the primary food source, supplement with live or frozen foods to enhance their health and coloration.
- Tankmates: Be cautious when choosing tankmates for your Betta. Peaceful, slow-moving species like Corydoras Catfish, snails, or shrimp can be compatible, but avoid aggressive or long-finned species that may provoke the Betta. Avoid other male Bettas and fin-nipping species.
Compatibility
Halfmoon Bettas are best kept alone or with peaceful species that won’t challenge their dominance. Potential tankmates include:
- Peaceful species such as Corydoras Catfish, small Tetras (e.g., Neon Tetras), or peaceful Snails and Shrimp (e.g., Amano Shrimp).
- Avoid aggressive fish or species with long, flowing fins like other male Bettas, Guppies, or Danios, as they can provoke the Betta.
- Female Bettas can sometimes be kept together in sororities (groups of 4-5 or more), but this requires careful monitoring to prevent aggression.
