The Green Severum

The Green Severum (*Heros efasciatus*) is a captivating freshwater cichlid native to the Amazon River basin in South America. Renowned for its unique coloration and gentle temperament, the Green Severum is a popular choice among aquarists looking for a visually appealing and interactive fish.

Physical Characteristics:

• Size: Green Severums typically grow to about 15-20 cm (6-8 inches) in length, making them a medium-sized cichlid species.
• Coloration:
  • Body: The Green Severum features a greenish-yellow body, often with hints of blue and gold. The coloration can vary among individuals, and they may also develop darker spots or patterns as they mature.
  • Fins: Their fins are generally clear to lightly tinted, with some individuals exhibiting subtle colors that enhance their overall appearance.
  • Shape: Green Severums have a deep, laterally compressed body shape typical of many cichlid species.

Behavior:

• Temperament: Green Severums are generally peaceful cichlids, but they can be territorial, especially during breeding. They may display aggression towards other cichlids or fish that invade their space.
• Activity Level: These fish are active swimmers and enjoy exploring their environment. They are known for their curious nature and may interact with their owners.
• Community Behavior: Green Severums can coexist with a variety of peaceful tankmates, provided they have enough space and hiding spots to reduce territorial disputes.

Aquarium Care:

• Tank Size: A minimum tank size of 200 liters (53 gallons) is recommended for a small group of Green Severums to provide ample swimming space and territories.
• Water Parameters:
  • Temperature: Green Severums thrive in warm water, with an ideal temperature range of 24°C to 28°C (75°F to 82°F).
  • pH: They prefer slightly acidic to neutral water, with a pH range of 6.0 to 7.5.
  • Hardness: Soft to moderately hard water, with a general hardness (GH) of 5-15 dGH, is ideal.
• Tank Setup:
  • Substrate and Decorations: A soft substrate, such as sand or fine gravel, is recommended. Green Severums appreciate a well-planted tank with plenty of hiding spots created by rocks, driftwood, and plants.
  • Lighting: Moderate lighting is best, as it encourages plant growth and mimics their natural habitat.
  • Filtration: A strong filtration system is necessary to maintain water quality, along with regular water changes (about 20% weekly).

Diet:

• Green Severums are omnivorous and require a varied diet to maintain their health and vibrant coloration. Their diet should include:
  • Pellets: High-quality cichlid pellets should form the staple of their diet.
  • Live or Frozen Foods: Offer live or frozen foods such as brine shrimp, bloodworms, and daphnia to provide essential protein and variety.
  • Vegetables: Blanched vegetables like zucchini, spinach, or peas can be included for added nutrition.

Tankmates:

• Green Severums can be housed with a variety of peaceful tankmates, including:
  • Medium-sized fish: Such as Tetras, Barbs, or Rainbowfish.
  • Other cichlids: Peaceful species that are similar in size.
  • Bottom-dwellers: Species like Corydoras or Plecos that won’t compete for territory.
• Avoid housing them with small or overly aggressive species, as this may lead to stress or injury.
