Betta Half Moon Assorted

Betta Half Moon Assorted 

Common Name

Half Moon Betta (Assorted Colors)

Scientific Name

Betta splendens

Origin

Southeast Asia (Thailand, Cambodia, Vietnam)
(Most Half Moon Bettas in the aquarium trade are captive-bred)

 

Appearance & Coloration

Betta Half Moon Assorted refers to Half Moon Bettas offered in a variety of colors and patterns. When fully flared, their tail fin spreads to a dramatic 180-degree half-moon shape. Color variations may include red, blue, white, black, yellow, marble, koi, butterfly, and multicolor combinations. Each fish is unique in pattern and intensity.

 

Fin Type

Long-finned Half Moon variety with large, flowing caudal, dorsal, and anal fins. While visually striking, these fins require calm water conditions to prevent stress or damage.

 

Temperament

Semi-aggressive to aggressive.
Male Half Moon Bettas are highly territorial and should be housed individually. Females are generally less aggressive but may still display territorial behavior.

 

Tank Size

Minimum 5 gallons recommended.
Larger tanks (10+ gallons) provide improved water stability and enrichment.

 

Tank Setup

• Heated freshwater aquarium

• Gentle filtration with minimal current

• Smooth décor and plants to prevent fin tearing

• Live or silk plants preferred over sharp artificial decorations

Floating plants and resting leaves are beneficial due to the Betta’s labyrinth breathing behavior.

 

Water Parameters

• Temperature: 25–28°C (77–82°F)

• pH: 6.5–7.5

• Ammonia/Nitrite: 0 ppm

• Nitrate: <20 ppm

Stable, warm water is essential to prevent stress, fin rot, and illness.

 

Filtration & Flow

Low flow only.
Strong currents can exhaust long-finned Half Moon Bettas.

 

Diet

Carnivorous.

 

Feeding

• High-quality Betta pellets or granules

• Frozen or live foods such as bloodworms, brine shrimp, daphnia

• Feed small amounts 1–2 times daily
  Avoid overfeeding to prevent bloating and swim bladder issues.

 

Compatibility

• Best kept alone

• Can be housed with peaceful, non-fin-nipping species (snails, shrimp, small schooling fish) in larger tanks

• Never house two male Bettas together

 

Health & Care Notes

• Susceptible to fin rot if water quality is poor

• Maintain consistent temperature and regular water changes (25–30% weekly)

• Observe fins regularly for tears or discoloration

 

Care Level

Easy to Moderate

Suitable for beginners when housed properly with heat, filtration, and stable water conditions.

 

Signs of Good Health

• Bright, vibrant coloration

• Active behavior and curiosity

• Full fin extension

• Strong feeding response

 

Signs of Stress or Illness

• Clamped or deteriorating fins

• Lethargy

• Loss of color

• Refusal to eat
