The Rotkeil Severum is widely considered one of the best “entry-level” large cichlids for hobbyists who want an intelligent, visually stunning fish without the high aggression levels associated with species like Oscars or Jack Dempseys.

Understanding Temperament & Tank Mates

Unlike many South American cichlids that aggressively guard large territories, the Rotkeil Severum is relatively peaceful and social. They thrive in community tanks alongside fish that are too large to be swallowed. Ideal tank mates include:

• Medium to large Tetras (such as Bleeding Heart or Congo Tetras)

• Plecostomus species and Corydoras catfish

• Other mild-mannered cichlids like Geophagus (Eartheaters) or Angelfish

Note for beginners: Avoid housing them with tiny, slender fish (like neon tetras or small guppies), as any fish small enough to fit into a Severum’s mouth may eventually be eaten.

Aquarium Setup & Aquascaping Considerations

Severums naturally inhabit blackwater regions of the Amazon, meaning they appreciate soft, slightly acidic water with plenty of hiding spots.

• Substrate: Smooth sand or fine gravel is recommended, as they enjoy sifting through the substrate for food.

• Decor: Driftwood, large rocks, and terracotta pots provide necessary shelter and security.

• Plant Safety: Rotkeil Severums are predominantly herbivorous in nature and love to graze on live aquarium plants. If you wish to keep live plants in their aquarium, choose tough, thick-leaved species like Anubias or Java Fern, and attach them firmly to driftwood or rocks rather than planting them directly in the substrate.

Feeding & Nutrition

To keep your Rotkeil Severum healthy and display its brightest red coloration, feed a balanced, omnivorous diet twice daily:

1. Staple Diet: High-quality sinking cichlid pellets or granulates rich in natural carotenoids (such as spirulina or astaxanthin).

2. Vegetable Supplementation: Regularly offer fresh blanched spinach, zucchini slices, shelled peas, or spirulina flakes to satisfy their natural craving for plant matter and prevent digestive blockages.

3. Protein Treats: Occasional feedings of frozen bloodworms, brine shrimp, or mysis shrimp will support healthy growth and body mass.
