Description
General Information:
The Red Shoulder Severum (Heros efasciatus) is a vibrant and peaceful cichlid native to the Amazon River Basin. Known for the red or orange markings around their head and shoulders, this species adds a splash of colour to any aquarium. Their calm demeanour makes them a great choice for both community tanks and species-specific setups.
Species Overview:
- Species: Heros efasciatus
- Common Name: Red Shoulder Severum
- Origin: Amazon River Basin, South America
- Diet: Omnivorous
- PH Range: 6.0–7.5
- Temperature: 24–28°C (75–82°F)
- Max Size: 8–10 inches (20–25 cm)
- Tank Size: Minimum 55 gallons
Water Quality:
Red Shoulder Severums thrive in soft to moderately hard water with a pH between 6.0 and 7.5. They prefer well-filtered aquariums with plenty of swimming space and hiding spots created by driftwood, rocks, and aquatic plants. Maintaining stable water conditions and performing regular water changes are essential for their health.
Feeding:
These omnivores enjoy a varied diet that includes high-quality pellets, flakes, vegetables, and live or frozen foods like bloodworms or brine shrimp. A balanced diet enhances their vibrant coloration. Feed them twice daily, ensuring they consume all the food within a few minutes.
Tank Mates:
Red Shoulder Severums are generally peaceful but can become territorial during breeding. They coexist well with other large, non-aggressive species such as Angelfish, Geophagus, and larger Tetras. Avoid keeping them with very small fish that could be mistaken for food.
Sexing:
Males are typically larger and more vividly coloured, with extended dorsal and anal fins. Females are slightly smaller and have rounder bodies. Males may also display more pronounced red markings around the head and shoulders.
Breeding:
Red Shoulder Severums are substrate spawners that lay eggs on flat surfaces like rocks or driftwood. Both parents guard the eggs and fry diligently. Breeding pairs can become territorial, so it’s best to provide ample space and hiding areas to reduce stress.
Maximum Size and Longevity:
These cichlids can reach up to 10 inches (25 cm) and live for 8–10 years in well-maintained aquariums. Providing a spacious tank with clean water and varied décor helps them thrive and reach their full potential.
Fun Fact:
Red Shoulder Severums are often compared to South American Angelfish due to their similar body shape and graceful swimming patterns, making them a popular centerpiece fish in community aquariums!
