What Is a Purple Cobra Guppy?

The Purple Cobra Guppy is a selectively bred variety of guppy (Poecilia reticulata) distinguished by its cobra-like body patterns and vivid purple hues. The term “cobra” refers to the intricate, snake-like markings along the body, which resemble the skin of a cobra snake. These markings are paired with the guppy’s bright purple, sometimes iridescent coloration, which makes them a dazzling addition to any aquarium.

This variety often showcases a purple-blue metallic sheen on the body, with intricate patterns that extend to the tail. The tail is usually large, fan-shaped, and often bears mosaic or snakeskin markings in darker purples or blacks.

Key Features of Purple Cobra Guppies

Here are some of the defining characteristics that make Purple Cobra Guppies unique:

1. Coloration

Their vibrant purple color can range from lavender to deep violet. In ideal conditions, males exhibit more intense hues, especially under bright lighting.

2. Cobra Pattern

This refers to the distinctive reticulated or snakeskin pattern that runs along the body. The pattern resembles the scales of a snake and is one of the most sought-after guppy patterns.

3. Tail Shape

Most Purple Cobra Guppies sport large, flowing tails—either fan-shaped, delta-shaped, or occasionally lyre tails—with patterned designs, often echoing the body’s cobra markings.

4. Size

• Males: 1.5 to 2 inches
• Females: 2 to 2.5 inches
  Males are smaller but more vividly colored, while females are larger and less colorful.

Ideal Tank Setup for Purple Cobra Guppies

Creating a healthy environment for your Purple Cobra Guppies is crucial to bringing out their best coloration and maintaining good health.

1. Tank Size

• Minimum tank size: 10 gallons (ideal for a small group of guppies)
• Larger tanks (20+ gallons) are recommended for breeding or community setups.

2. Water Parameters

• Temperature: 72°F to 82°F (22°C to 28°C)
• pH: 6.8 to 7.8
• Hardness: 8–12 dGH
• Ammonia/Nitrite: 0 ppm
• Nitrate: <20 ppm

Guppies are relatively hardy but prefer stable, clean water. Regular partial water changes (25% weekly) are essential.

3. Filtration and Aeration

• Use a gentle filter to maintain water quality without causing strong currents.
• Sponge filters are ideal, especially in breeding tanks.
• Ensure good oxygenation through surface agitation or an air stone.

4. Substrate and Décor

• Fine gravel or sand substrate
• Live plants (Java moss, guppy grass, hornwort)
• Rocks, driftwood, and hiding spots
• Avoid sharp decorations that may damage their fins.

5. Lighting

Moderate to high lighting enhances their coloration. Choose aquarium lights that highlight purples and blues to make their color pop.

Feeding Purple Cobra Guppies

A balanced diet helps maintain the health, coloration, and breeding potential of your Purple Cobra Guppies.

Ideal Diet Includes:

• High-quality flake food: Formulated for tropical fish or guppies
• Micro pellets
• Live food: Brine shrimp, daphnia, mosquito larvae
• Frozen food: Bloodworms, tubifex, and mysis shrimp
• Vegetables: Blanched spinach, zucchini, or peas (for fiber)

Feeding Schedule:
Feed small amounts 2–3 times daily. Avoid overfeeding, as uneaten food can degrade water quality.

Temperament and Tank Mates

Purple Cobra Guppies are peaceful and social fish. They enjoy the company of other guppies and similarly sized community fish.

Ideal Tank Mates:

• Other guppies
• Corydoras catfish
• Neon tetras
• Harlequin rasboras
• Platies
• Mollies
• Snails (Nerite, Mystery)
• Shrimp (Cherry, Amano)

Avoid Aggressive Fish:

Stay away from fin-nippers like tiger barbs or large cichlids that may bully or harm your guppies.

Breeding Purple Cobra Guppies

Breeding guppies is straightforward, and the Purple Cobra variety is no exception. In fact, they’re prolific breeders, making them a great option for those wanting to breed ornamental fish.

1. Sexing Guppies

• Males: Smaller, colorful, with a gonopodium (modified anal fin)
• Females: Larger, rounded bellies, gravid spot near the rear

2. Breeding Tank Setup

• 10–20 gallon tank
• Live plants like Java moss for fry hiding
• Sponge filter to prevent fry suction

3. Breeding Process

• Keep a ratio of 1 male to 2–3 females
• Females can store sperm and give birth multiple times after a single mating
• Gestation period: ~21–30 days
• Each female can deliver 20–100 fry

4. Raising the Fry

• Separate fry from adults to avoid predation
• Feed baby brine shrimp or crushed flakes 3–4 times daily
• Perform frequent water changes to maintain water quality

Selective breeding over generations is essential to retain the deep purple coloration and strong cobra pattern in offspring.

1. Ich (White Spot Disease)

• Symptoms: White spots, scratching on surfaces
• Treatment: Raise temperature, use Ich medication

2. Fin Rot

• Caused by poor water quality or injury
• Prevention: Maintain clean water, avoid overcrowding

3. Internal Parasites
