Melanochromis Johannii

Introduction

The Melanochromis Johannii, also known as the Electric Blue Johanni, is a strikingly colored cichlid native to the rocky shorelines of Lake Malawi in Africa. This species is highly sought after in the aquarium hobby due to its vibrant blue and black coloration in males and bright orange-yellow hues in females. As a member of the Mbuna group, it is an active and territorial fish that thrives in a well-structured aquarium with plenty of hiding spots.

Scientific Name

 Melanochromis johannii

Common Names

Electric Blue Johanni, Blue Johanni Cichlid

Water Quality and Temperature

• Temperature: Maintain a range of 75°F to 82°F (24°C to 28°C) to replicate its natural tropical habitat.
• pH Level: 7.8 to 8.6, as they prefer alkaline water conditions.
• Hardness: 10 to 20 dGH to match the mineral-rich waters of Lake Malawi.
• Filtration: Strong filtration and regular water changes are essential to keep water quality high, as these fish are sensitive to poor conditions.

Feeding

• Diet: Primarily herbivorous, the Melanochromis Johannii requires a diet rich in plant-based foods.
• Pellets and Flakes: High-quality cichlid pellets or spirulina-based flakes.
• Vegetables: Blanched spinach, zucchini, and peas can be included.
• Avoid: Avoid protein-rich foods like bloodworms and excessive meaty foods, as they can cause digestive issues.

Tank Mates

• Compatible Species: Other Mbuna cichlids such as Yellow Labs (Labidochromis caeruleus), Red Zebra Cichlids (Maylandia estherae), or other similarly sized and temperament-matching species.
• Avoid: Small, slow-moving, or timid fish, as Johannii are territorial and aggressive. Do not mix with overly aggressive species like Melanochromis auratus to prevent conflicts.

Substrates and Tank Decorations

• Substrate: A sandy or fine gravel substrate is best to mimic their natural environment.
• Decor: Provide plenty of rock formations, caves, and hiding spots to help reduce aggression and create territories.
• Plants: Live plants are generally not recommended, as Mbuna cichlids tend to dig and uproot them. If adding plants, choose hardy options like Anubias or Java Fern attached to rocks.

Sexing

• Males: Bright electric blue with black horizontal stripes.
• Females: Yellow to orange in coloration, making them easy to distinguish from males.

Breeding

• Type: Mouthbrooder – females carry fertilized eggs in their mouths until they hatch.
• Breeding Behavior: Males establish territories and display aggressive courtship behaviors. Once the female lays eggs, she scoops them into her mouth, where the male fertilizes them.
• Care of Fry: After 2-3 weeks, the female releases fully formed fry. Fry can be fed crushed flake food or baby brine shrimp.

Maximum Size and Longevity

• Size: Typically grows to about 4-5 inches (10-13 cm).
• Lifespan: With proper care, they can live up to 8-10 years.

General Information

The Melanochromis Johannii is an aggressive and territorial cichlid best suited for cichlid-specific aquariums with similarly tempered tank mates. Its stunning coloration and dynamic behavior make it a favorite among Mbuna enthusiasts. Providing a well-structured environment with caves and rockwork will help minimize aggression and promote natural behaviors.

A Fun Fact

Like other Mbuna cichlids, the Melanochromis Johannii uses a unique method of breeding called “mouthbrooding,” where the female protects and nurtures her eggs in her mouth until they hatch, ensuring a higher survival rate for the fry.
