Common Names: Female Halfmoon Betta, Halfmoon Betta
Family: Osphronemidae
Origin: Native to Southeast Asia, particularly Thailand, Cambodia, and Vietnam.
Physical Description
Coloration: Female Halfmoon Bettas come in a wide array of colors, including solid shades, bi-color patterns, and marbled designs. Their colors can range from vibrant reds and blues to softer pastel hues.
Body Shape: Like other Betta species, they have a slender, elongated body, but their overall appearance is enhanced by their impressive fins.
Fins:
Halfmoon Tail: The defining feature of the Halfmoon Betta is its tail, which is broad and circular, forming a 180-degree angle when fully spread. This tail shape gives them a stunning, fan-like appearance.
Dorsal and Anal Fins: These fins are also long and flowing, often complementing the tail with beautiful coloration and patterns.
Size: Female Bettas typically grow to about 2 to 3 inches (5 to 7.5 cm) in length.
Behavior
Temperament: Female Halfmoon Bettas are generally more docile than males, but they can still exhibit territorial behaviors, especially in smaller tanks. They are known for being less aggressive than many other Betta varieties.
Social Structure: While females can be kept in groups (sororities), it's essential to provide enough space and hiding spots to minimize aggression. A minimum tank size of 20 gallons is recommended for a group of females.
Activity Level: These fish are active swimmers and enjoy exploring their environment. They display interesting behaviors, including fin flaring and social interactions with tank mates.
Habitat
Natural Habitat: In the wild, Betta fish inhabit shallow, slow-moving waters like rice paddies, swamps, and marshes, where they find shelter among dense vegetation.
Aquarium Setup: A well-planted tank with plenty of hiding spots using live plants, driftwood, or decorations is ideal. A minimum tank size of 5 gallons is recommended, but larger tanks are preferable for better water quality and space.
Diet
Feeding: Female Halfmoon Bettas are carnivorous and require a high-protein diet. They accept high-quality Betta pellets, flakes, freeze-dried foods, and occasional live or frozen foods (such as bloodworms, brine shrimp, and daphnia).
Feeding Frequency: Feed them once or twice a day, providing only as much food as they can consume within a few minutes to avoid overfeeding.
Breeding
Breeding Type: Female Halfmoon Bettas can breed with males that create bubble nests at the water's surface.
Nesting: During breeding, the male will display courtship behaviors to attract the female. Once she is receptive, they will engage in a mating ritual.
Fry Care: After spawning, the male will care for the eggs, which typically hatch within 24 to 48 hours. Once the fry are free-swimming, the male should be removed to prevent aggression towards them.
Care Requirements
Tank Size: A minimum of 5 gallons is recommended for a single female, with larger tanks being preferable for sororities.
Water Parameters:
Temperature: 75°F to 82°F (24°C to 28°C)
pH Level: 6.5 to 7.5 (slightly acidic to neutral)
Hardness: 5 to 15 dGH
Filtration: Use a gentle filter to maintain water quality. Regular water changes (about 25% weekly) are essential to keep the water clean and healthy.
Compatibility
Tank Mates: Female Halfmoon Bettas can be kept with other peaceful community fish such as tetras, rasboras, and snails. Avoid aggressive species and other male Bettas to prevent fighting.
Behavior with Others: Always monitor the tank for signs of aggression, especially when introducing new tank mates or keeping multiple females.
Lifespan
Lifespan: With proper care, female Halfmoon Bettas can live for about 3 to 5 years in captivity.
Interesting Facts
