Appearance & Coloration

The Galaxy Koi Plakat Betta is a short-finned Betta prized for its striking, koi-inspired coloration. Patterns typically feature a mix of red, white, black, and sometimes metallic blue, resembling the unique markings of koi fish. “Galaxy” variants often have subtle iridescent or metallic spots, giving a sparkling or starlike effect across the body. Each fish is unique, making them highly collectible.

 

Fin Type

• Plakat (short-finned): Smooth, streamlined fins allow for better swimming ability and more hardy care compared to long-finned Bettas.

• Anal, dorsal, and caudal fins are proportionally smaller, making them less prone to tearing.

 

Temperament

Semi-aggressive to aggressive.
Male Galaxy Koi Plakats are territorial and must be housed alone. Females may be kept in groups but require monitoring for aggression.

 

Tank Size

Minimum 5 gallons recommended.
Larger tanks (10+ gallons) improve stability and provide swimming space.

 

Tank Setup

• Heated freshwater aquarium

• Gentle filtration with low flow

• Smooth décor and plants

• Floating plants and resting areas are beneficial

Live or silk plants are preferred to protect fins.

 

Water Parameters

• Temperature: 25–28°C (77–82°F)

• pH: 6.5–7.5

• Ammonia/Nitrite: 0 ppm

• Nitrate: <20 ppm

Stable water is critical for health and color maintenance.

 

Filtration & Flow

Low flow only.
Plakats are short-finned but still prefer gentle water movement.

 

Diet

Carnivorous.

 

Feeding

• High-quality Betta pellets or granules

• Frozen/live foods: bloodworms, brine shrimp, daphnia

• Feed small portions 1–2 times daily

Avoid overfeeding to prevent bloating and swim bladder problems.

 

Compatibility

• Best housed alone

• Can be kept with peaceful, non-fin-nipping species in larger aquariums

• Never house two males together

 

Health & Care Notes

• More hardy than long-finned Bettas, but still susceptible to stress if water quality declines

• Regular water changes (25–30% weekly) recommended

• Observe fins and body for color changes, clamping, or injury

 

Care Level

Easy–Moderate

Plakats are generally beginner-friendly due to their shorter fins and hardier nature.

 

Signs of Good Health

• Bright, vibrant coloration

• Active swimming and curiosity

• Healthy fins and body

• Strong feeding response

 

Signs of Stress or Illness

• Clamped fins

• Lethargy

• Loss of color

• Refusal to eat

 

Fun Fact 

Galaxy Koi Plakat Bettas get their name from a combination of koi-like body patterns and subtle metallic “galaxy” spots, giving them a sparkling, starlike appearance that makes each fish unique.
