Green Severum (Heros severus) – Care Guide & Tank Requirements

The Green Severum (Heros severus) is a stunning, semi-peaceful cichlid that adds elegance and personality to any aquarium. Known for its vibrant green coloration and distinctive banding, this species is a favorite among freshwater fish keepers. If you’re considering adding a Green Severum to your tank, here’s everything you need to know about their care.

Tank Setup & Water Conditions

To ensure your Green Severum thrives, provide a spacious tank with clean, well-filtered water.

• Tank Size: Minimum 55 gallons for a single fish, 75+ gallons for a pair or community setup.

• Water Temperature: 75-82°F (24-28°C)

• pH Level: 6.0-7.5

• Water Hardness: 4-15 dGH

• Substrate & Decor: Soft sand or fine gravel, driftwood, rocks, and live plants (though some nibbling may occur).

Temperament & Compatible Tank Mates

Green Severums are generally peaceful but can become territorial, especially during breeding. They do well with other medium to large semi-aggressive fish.

• Good Tank Mates: Angelfish, Geophagus, larger tetras, plecos, and peaceful catfish.

• Avoid: Small, delicate fish (like neon tetras) and highly aggressive species.

Diet & Nutrition

As omnivores, Green Severums need a balanced diet of plant-based and protein-rich foods.

• Staple Diet: High-quality pellets or cichlid flakes.

• Treats: Bloodworms, brine shrimp, and small insects.

• Vegetation: Blanched zucchini, spinach, or peas to support digestive health.

Breeding & Reproduction

Green Severums form strong monogamous pairs and are attentive parents.

• Egg Laying: They prefer flat surfaces like rocks for spawning.

• Parental Care: Both parents protect the eggs and fry.

• Tip: Provide a peaceful environment to encourage breeding behavior.

Why Choose a Green Severum?

Green Severums are perfect for hobbyists looking for an intelligent and interactive fish. Their stunning colors, manageable temperament, and interesting behaviors make them an excellent addition to medium-to-large aquariums.
