Appearance & Coloration

The Fancy Half Moon Male Betta is known for its extravagant fins and vivid coloration. When fully flared, the caudal fin spreads to a perfect 180-degree half-moon shape. “Fancy” Bettas display a wide range of eye-catching colors and patterns, including multicolor, marble, koi, butterfly, and iridescent combinations. Each fish is unique in coloration and pattern.

 

Fin Type

Long-finned Half Moon variety with large, flowing caudal, dorsal, and anal fins. These delicate fins require calm water conditions to prevent tearing or stress.

 

Temperament

Semi-aggressive to aggressive.
Male Fancy Half Moon Bettas are highly territorial and should be housed individually. They may flare or show aggression toward similar-looking fish.

 

Tank Size

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

 

Tank Setup

• Heated freshwater aquarium

• Gentle filtration with low flow

• Smooth décor and plants to protect fins

• Live or silk plants preferred over sharp artificial décor

Floating plants and Betta hammocks are beneficial resting areas.

 

Water Parameters

• Temperature: 25–28°C (77–82°F)

• pH: 6.5–7.5

• Ammonia/Nitrite: 0 ppm

Feeding
