What Is a Black Dragon Guppy?

The Black Dragon Guppy is a selectively bred strain of the Poecilia reticulata, more commonly known as the guppy. This specific variety is distinguished by its deep black body, dragon-scale-like texture, and large, flowing fins that often resemble a dragon’s tail or wings. The name “Black Dragon” is inspired by its resemblance to mythical creatures from Asian folklore—powerful, elegant, and mysterious.

This guppy variety is not only admired for its appearance but also for its hardiness and adaptability, making it a favorite among hobbyists who want both beauty and resilience in their tanks.

Origins and Breeding History

The guppy was first discovered in the 1860s and originates from parts of South America. Over the decades, aquarists and breeders around the world have developed a wide range of guppy strains, including the Black Dragon Guppy.

The Black Dragon strain was created through selective breeding—choosing guppies with deep black coloration and enhancing the pattern and texture of their scales. Breeders often crossed guppies with dark Moscow strains and other dragon-scale varieties to develop the deep, glossy black coloration and the metallic, armored look of the scales.

This guppy is not found in the wild; it is a product of human innovation in the ornamental fish industry.

Physical Characteristics

The Black Dragon Guppy has several defining traits that make it stand out:

1. Coloration

The dominant color is a rich, velvety black, often accompanied by subtle blue, green, or purple iridescence depending on the lighting. Some individuals may display dragon-scale patterns on their flanks, giving them a textured, almost armored appearance.

2. Fins and Tail

One of the most eye-catching features is the expansive tail fin. It is usually fan-shaped or delta-shaped and flows gracefully when the guppy swims. The tail and dorsal fins are typically black or dark with slight transparency, contributing to the “dragon” aesthetic.

3. Size

Black Dragon Guppies are similar in size to other guppies:

Males: 1.5 to 2 inches (3.8 to 5 cm)
Females: 2 to 2.5 inches (5 to 6.3 cm)

4. Sexual Dimorphism

As with most guppies, males are more colorful and have longer fins, while females are larger and more robust with a rounder abdomen.

Behavior and Temperament

Black Dragon Guppies are peaceful and social fish. They are ideal for community aquariums and thrive when kept in groups. Males can sometimes be a bit persistent when courting females, so it’s recommended to keep a ratio of one male to two or three females to reduce stress.

These guppies are active swimmers, constantly exploring their environment and interacting with tank mates. Their non-aggressive nature makes them compatible with many other peaceful species.

Aquarium Requirements

1. Tank Size

A minimum of 10 gallons is recommended for a small group of Black Dragon Guppies. A larger tank will provide more swimming space and help maintain water quality.

2. Water Parameters

Maintaining stable water conditions is key to keeping your guppies healthy:

Temperature: 72°F to 82°F (22°C to 28°C)
pH: 6.8 to 7.8
Hardness: 8–12 dGH

Use a water conditioner to remove chlorine and heavy metals, and perform regular water changes (about 25% weekly).

3. Filtration and Aeration

A sponge filter or hang-on-back filter is ideal. Ensure good water circulation without creating strong currents. Guppies also appreciate well-oxygenated water.

4. Lighting

Moderate lighting will enhance the iridescent hues of the Black Dragon Guppy, especially the shimmering undertones in its dark scales.

5. Substrate and Decor

Use a dark substrate to enhance the contrast of the guppy’s black coloration. Include live or artificial plants for hiding spots, and decorations to mimic a natural habitat.

Diet and Nutrition

Black Dragon Guppies are omnivores and require a balanced diet to maintain their coloration and health. A varied diet includes:

1. Staple Foods

High-quality flakes or pellets designed for tropical fish

2. Protein-Rich Foods

Live or frozen brine shrimp
Daphnia
Bloodworms

3. Vegetable Matter

Blanched spinach or zucchini
Algae wafers

Feed small amounts 2–3 times daily, and avoid overfeeding to prevent water quality issues.

Breeding Black Dragon Guppies

Breeding guppies is relatively easy due to their live-bearing nature. Here’s a quick guide:

1. Sexing

Males: Smaller, more colorful, with a gonopodium (modified anal fin)
Females: Larger, less colorful, with a visible gravid spot near the abdomen

2. Breeding Tank Setup

Use a separate tank for breeding if possible. Add dense plants like Java moss or use a breeding box to protect the fry.

3. Gestation

Guppy females give birth approximately every 28 days, producing 20–50 fry per batch.

4. Fry Care

Fry are born fully formed and ready to swim. Feed them crushed flakes, baby brine shrimp, or commercial fry food. Keep them separated from adult fish to avoid predation.

Common Health Issues

Though hardy, Black Dragon Guppies can face a few health challenges:

1. Ich (White Spot Disease)

Symptoms: White spots on fins and body
Treatment: Increase temperature slightly, use Ich medication

2. Fin Rot

Symptoms: Frayed or discolored fins
Treatment: Improve water quality, use antibacterial treatments

3. Swim Bladder Disease

Symptoms: Erratic swimming or floating
Treatment: Isolate affected fish, feed peas (after removing skin), improve diet

Always quarantine new fish before introducing them to the main tank.

Tank Mates for Black Dragon Guppies

Choose peaceful, non-fin-nipping tank mates such as:

Neon Tetras
Corydoras Catfish
Mollies
Swordtails
Snails
Shrimp (e.g., Cherry Shrimp or Amano Shrimp)

Avoid aggressive fish like Tiger Barbs or larger Cichlids.
