Origin and Background

The Black Cobra Guppy is a result of selective breeding of guppies (Poecilia reticulata), which are native to South America—specifically Venezuela, Guyana, and northern Brazil. Breeders developed the “Cobra” pattern to resemble the scales of a snake, with interwoven, net-like markings. The black variant enhances the dramatic look, making this strain one of the most striking guppies in the hobby.

Appearance and Coloration

The Black Cobra Guppy is characterized by:

• Body Pattern: Snake-like “cobra” markings in shades of black and gold, sometimes with hints of green or blue.
• Tail Shape: Usually has a fan-shaped caudal fin, but variations like delta tail or lyretail exist.
• Size: Males grow up to 1.5–2 inches, while females can reach 2–2.5 inches.
• Sexual Dimorphism: Males are smaller, more colorful, and have longer fins, while females are larger and less vibrant.
• Eye Color: Often dark, which enhances their exotic appearance.

Temperament and Behavior

Black Cobra Guppies are peaceful, social, and active swimmers. They:

• Get along well with other small, non-aggressive fish.
• Enjoy swimming in all areas of the tank.
• Are curious and will explore plants, decorations, and caves.
• Do best in groups of at least 6, as they are schooling fish.

Pro Tip: Keep more females than males (ratio 2:1) to prevent male harassment.
