The Green Male Cobra Guppy is a visually striking variety of guppy known for its unique “cobra” pattern and iridescent green coloration. This pattern, which resembles snake-like markings, often extends across the body and tail, creating a dramatic and eye-catching appearance. These guppies are highly prized for their vibrant colors, flowing fins, and peaceful temperament, making them a popular choice for community tanks. Male Green Cobra Guppies are typically more colorful than females, displaying an impressive combination of green, black, and sometimes blue highlights. These fish usually grow to about 1.5-2 inches (4-5 cm) and can live for 2-3 years in captivity with proper care.
Habitat and Tank Requirements:
In the wild, guppies inhabit slow-moving freshwater streams and ponds. In an aquarium, Green Cobra Guppies thrive in warm, clean water with plenty of plants and open swimming areas.
Tank Size and Water Parameters:
| PARAMETER | RECOMMENDED |
|---|---|
| Tank Size | Minimum 40 litres |
| Temperature | 72-82°F (22-28°C) |

Green Cobra Guppies are hardy and adaptable to a range of water conditions, though they prefer stable environments. A well-planted tank with a substrate of fine gravel or sand provides both cover and grazing surfaces. Live plants like Java moss, Anubias, or floating plants add hiding spots and create a natural environment. Guppies enjoy moderate water flow, so a gentle filter is ideal, along with regular water changes to maintain water quality.
