Origin and Background
The Cobra Endler Guppy is a hybrid fish that originates from crossbreeding between Endler’s Livebearer (Poecilia wingei) and the Cobra-patterned Guppy (Poecilia reticulata). This hybridization brings together the vibrant coloration of the Endler and the intricate body patterns of the Cobra Guppy, resulting in a stunning and hardy fish.
- Endler’s Livebearer Origin: Found naturally in Laguna de Patos, Venezuela. Known for its small size and neon-like colors.
- Cobra Guppy Origin: A selectively bred variety of guppy famous for its “snakeskin” pattern that resembles a cobra’s scales.
By blending these two species, breeders have created a hybrid that maintains the energy and small size of Endlers while adding the mesmerizing color variety of guppies. The result is a truly unique fish admired in aquascapes worldwide.

The Cobra Endler Guppy stands out for its intricate body patterns and dazzling coloration. These fish are incredibly diverse in appearance, depending on their genetic lineage and breeding focus.
Key Physical Traits:
- Body Shape: Slim and elongated like Endler’s Livebearers.
- Size: Males typically grow up to 1 inch (2.5 cm), while females can reach 1.5 inches (3.8 cm).

Every Cobra Endler Guppy looks slightly different, making each one a living piece of aquatic art.
Male vs. Female Cobra Endler Guppy
Males:

- Display vivid Cobra markings across the body.
- Have a gonopodium (modified anal fin used for breeding).
Females:
- Larger and rounder-bodied.

In a mixed community tank, males often display their colors more intensely, especially when trying to court females.
Cobra Endler Guppy Behavior
These guppies are peaceful, active, and social, making them excellent community fish. They spend much of their time exploring, displaying, and interacting with other tank mates.
- Temperament: Non-aggressive, suitable for peaceful aquariums.
- Schooling Behavior: Prefer to live in small groups (at least 5–6 fish).
- Activity Level: Very active swimmers that add constant movement and life to the aquarium.
- Social Interaction: Males often engage in playful chasing and displaying behavior, especially during mating periods.
Since they are small and friendly, they should not be housed with larger or aggressive fish.
Ideal Tank Setup for Cobra Endler Guppy
A well-maintained tank environment is essential for keeping your Cobra Endler Guppies healthy and vibrant. Although they are hardy and adaptable, providing optimal conditions ensures long-term well-being and color enhancement.
1. Tank Size
- Minimum Tank Size: 10 gallons (38 liters) for a small colony.
- For breeding or larger groups, 20 gallons or more is ideal.
2. Water Parameters
- Temperature: 72–82°F (22–28°C)
- pH Level: 6.8–8.0
- Hardness: 8–12 dGH
- Ammonia/Nitrite: 0 ppm
- Nitrate: Below 20 ppm
Stable water parameters are more important than perfect numbers. Avoid sudden fluctuations in temperature or pH.
3. Filtration and Aeration
- Use a gentle sponge filter or hang-on-back filter.
- Ensure moderate water flow—too strong a current can stress small guppies.
- Aeration helps maintain oxygen-rich water, especially in warmer tanks.
4. Substrate and Decor
- Fine gravel or sand substrate.
- Add live plants like Java Moss, Anubias, or Water Sprite.
- Provide hiding spots using driftwood, rocks, and decorations.
- Open swimming areas are crucial since these fish love to explore.
5. Lighting
- Moderate lighting enhances their color display.
- Too much light can cause algae growth; balance with floating plants.
6. Tank Cover
Always keep the tank covered—Cobra Endler Guppies are known jumpers, especially when startled
Diet and Feeding
The Cobra Endler Guppy is an omnivorous species with a strong appetite for both animal and plant-based foods. To maintain their bright colors and energy, a balanced and varied diet is essential.
Recommended Foods:
- Flake Food: High-quality guppy or tropical flakes.
- Pellets: Micro pellets suitable for small livebearers.
- Frozen Foods: Bloodworms, daphnia, brine shrimp, and mosquito larvae.
- Live Foods: Infusoria, microworms, and live brine shrimp to enhance coloration.
- Vegetable Matter: Blanched spinach, zucchini, or spirulina flakes.
Feeding Tips:
- Feed small portions 2–3 times daily.
- Remove uneaten food after a few minutes to prevent water pollution.
- Supplement their diet with natural algae growth for fiber and micronutrients.
A well-fed Cobra Endler Guppy exhibits richer colors and remains more active and healthy.
Tank Mates for Cobra Endler Guppy
Because of their peaceful temperament, Cobra Endler Guppies can live harmoniously with other small, non-aggressive species.
Ideal Tank Mates:
- Neon Tetras
- Harlequin Rasboras
- Corydoras Catfish
- Otocinclus
- Cherry Shrimp
- Snails (Nerite or Mystery Snails)
- Other Guppy or Endler varieties
Tank Mates to Avoid:
- Aggressive fish like Barbs, Cichlids, or Bettas.
- Large species that may see guppies as food.
Keeping them with other peaceful fish ensures a calm and thriving community tank.
Breeding Cobra Endler Guppies
One of the biggest joys of owning Cobra Endler Guppies is how easily they breed. Like all livebearers, they give birth to free-swimming fry instead of laying eggs.
1. Breeding Conditions
- Tank Size: 10–20 gallons.
- Water Temperature: 78–80°F (25–27°C) encourages breeding.
- Ratio: 1 male for every 2–3 females (to reduce stress on females).
2. Mating Behavior
Males constantly display their vibrant colors and chase females to mate. Once fertilized, the female can store sperm for multiple broods, giving birth several times without remating.
3. Gestation and Birth
- Gestation Period: 3–4 weeks.
- Fry Count: 10–30 per birth.
- Fry are born fully formed and start swimming and feeding immediately.
4. Fry Care
- Move the pregnant female to a breeding box or separate nursery tank.
- After birth, remove the mother to prevent her from eating the fry.
- Feed fry with infusoria, crushed flakes, or baby brine shrimp.
- Perform frequent small water changes to maintain cleanliness.
Cobra Endler Guppies breed prolifically, and with minimal care, you can grow a thriving colony.
