Originating from the Amazon River Basin, these cichlids add a vibrant touch of the tropics to any freshwater tank. This comprehensive guide covers everything you need to know about Green Severum Cichlids, including their care, tank requirements, feeding habits, breeding, and compatibility with other fish.

Green Severum Cichlid Overview

Characteristics and Appearance

Green Severum Cichlids are easily recognizable by their beautiful green coloration, which can range from olive to emerald, often with a metallic sheen. They have an oval-shaped body and long, flowing fins, which can develop red or orange edges as they mature. These fish can grow up to 8 inches (20 cm) in length, making them a medium to large-sized cichlid.

Natural Habitat

In the wild, Green Severum Cichlids are found in slow-moving rivers and streams with plenty of vegetation. They thrive in environments with soft, slightly acidic water and abundant plant life, which provides hiding spots and grazing opportunities.

Green Severum Cichlid Size and Growth

Full Grown Green Severum Cichlid

Adult Green Severum Cichlids typically reach lengths of 6-8 inches (15-20 cm). In optimal conditions, some individuals can grow up to 10 inches (25 cm). Their growth rate is influenced by several factors, including diet, water quality, and tank size.

Factors Affecting Growth

• Diet: A balanced diet rich in proteins and nutrients supports healthy growth.
• Tank Size: Spacious tanks allow for better swimming and less stress, promoting growth.
• Water Quality: Consistently clean water helps prevent disease and supports overall health.
• Genetics: Inherited traits can play a significant role in determining the ultimate size of the fish.

Green Severum Cichlid Tank Requirements

Tank Size

Green Severum Cichlids require a spacious aquarium to thrive. A minimum tank size of 55 gallons is recommended for a single Severum. If you plan to keep a pair or a community of Severums, a tank of at least 75-100 gallons is advisable to provide ample space and reduce territorial disputes.

Tank Setup

Creating an ideal environment for Green Severum Cichlids involves mimicking their natural habitat:

• Substrate: Use sand or fine gravel to replicate riverbeds.
• Decorations: Include driftwood, rocks, and caves for hiding spots.
• Plants: Incorporate hardy plants like Anubias or Java Fern, though Severums may occasionally nibble on them.
• Filtration: Ensure strong filtration to maintain water quality.
• Water Parameters: Maintain a temperature of 75-84°F (24-29°C), pH between 6.0-7.5, and moderate hardness (4-15 dGH).

Green Severum Cichlid Tank Mates

Suitable Tank Mates

Green Severum Cichlids are relatively peaceful compared to other cichlids, but choosing compatible tank mates is crucial. Suitable companions include:

• Other Cichlids: Medium-sized, non-aggressive species like Blue Acara or Firemouth Cichlids.
• Catfish: Peaceful bottom dwellers such as Corydoras or Plecos.
• Tetras: Larger, fast-swimming species like Congo Tetras or Buenos Aires Tetras.
• Gouramis: Medium-sized species like Pearl Gouramis or Three-spot Gouramis.

Incompatible Species

Avoid keeping Green Severum Cichlids with overly aggressive or significantly smaller fish to prevent bullying or predation. Incompatible species include:

• Small Tetras or Guppies: These can be seen as food.
• Aggressive Cichlids: Like Oscars or Jack Dempseys, which may outcompete or bully Severums.
• Fragile Species: Such as Discus or Angelfish, which may not withstand the active nature of Severums.

Green Severum Cichlid Diet and Feeding

Dietary Requirements

Green Severum Cichlids are omnivorous and benefit from a varied diet. Providing a balanced mix of foods ensures they receive all necessary nutrients:

• High-Quality Pellets: Specifically formulated for cichlids.
• Live or Frozen Foods: Such as brine shrimp, bloodworms, and daphnia for protein.
• Vegetables: Blanched spinach, peas, and zucchini for fiber and vitamins.

Feeding Frequency

Feed Green Severum Cichlids 2-3 times a day, offering only what they can consume within a few minutes to avoid overfeeding and water pollution.

Green Severum Cichlid Health and Common Diseases

Health Maintenance

Green Severum Cichlids are generally hardy, but maintaining optimal health involves regular monitoring and proper care:

• Water Quality: Perform regular water changes (20-30% weekly) to keep the water clean and free from toxins.
• Diet: Provide a varied and nutritious diet to support immune function.
• Observation: Regularly check for signs of illness or stress, such as changes in color, behavior, or appetite.

Common Diseases

• Ich (White Spot Disease): Characterized by white spots on the body and fins, treatable with medication and raising the water temperature.
• Fin Rot: Caused by poor water quality, leading to frayed fins, treatable with improved conditions and medication.
• Hole-in-the-Head Disease: Linked to poor diet and water quality, treatable with enhanced nutrition and water conditions.

Breeding Green Severum Cichlid

Breeding Behavior

Breeding Green Severum Cichlids can be a rewarding endeavor. They are substrate spawners, meaning they lay eggs on flat surfaces such as rocks or the tank glass. Key points to consider include:

• Pair Selection: Choose a healthy, compatible pair.
• Spawning Conditions: Provide flat surfaces, maintain optimal water conditions, and ensure a balanced diet.
• Parental Care: Both parents guard and fan the eggs to ensure oxygenation and protect them from predators.

Raising Fry

Once the eggs hatch, the fry require special care:

• Feeding: Provide infusoria or commercially available fry food initially, transitioning to finely crushed flakes or brine shrimp as they grow.
• Water Quality: Maintain pristine water conditions with frequent water changes.
• Separation: Consider separating the fry from adult fish to prevent predation.
