Short Description

The Severum Cichlid (Heros severus), also known as the Banded Cichlid or Hero Cichlid, is a popular aquarium fish native to South America. Known for its vibrant color variations, including green, gold, and red-spotted varieties, the Severum is a relatively peaceful species despite its size. It thrives in calm, well-planted tanks with plenty of hiding spots and makes an excellent centerpiece for South American biotope setups.

Origin

Native to the Amazon River Basin in South America, Severums are typically found in slow-moving or still waters with ample submerged vegetation and natural debris, such as branches and fallen leaves. These environments provide them with cover and an abundance of food sources.

Tank Requirements

Severums require a spacious aquarium of at least 200 liters (approximately 50 gallons) due to their size, which can reach up to 30 cm (11.81 inches). Maintain a water temperature of 24-29°C (75.2-84.2°F) and a pH level between 6 and 7.5. Water hardness should range from 4-18°N (71.43-321.43 ppm). A soft substrate, live plants, driftwood, and rocks will help mimic their natural habitat and provide essential hiding spaces.

Food

Severums are omnivorous and thrive on a varied diet. Offer high-quality cichlid pellets or flakes supplemented with fresh vegetables such as blanched spinach, zucchini, and cucumber to ensure balanced nutrition. Treat them occasionally with live or frozen foods, such as bloodworms or brine shrimp, but avoid overfeeding to maintain their health.

Compatibility

Severums are generally peaceful and can coexist with other similar-sized or non-aggressive fish. Suitable tankmates include other South American species like Angelfish (Pterophyllum scalare), Corydoras catfish, and larger Tetras. Avoid housing them with overly aggressive or fin-nipping species to prevent stress or injury.

Sexing

Sexing Severums can be challenging. Males often exhibit brighter colors and more pronounced facial markings compared to females. These differences become more apparent during breeding, as males display more vibrant hues to attract females.

Breeding

Severums are delayed mouthbrooders. The female lays eggs on a clean surface like a flat rock, which the male fertilizes. Afterward, the female gathers the eggs in her mouth and incubates them until hatching. The fry remain in her mouth for several days for added protection. During this time, the female will not eat, focusing entirely on caring for her brood.

Lifespan

With proper care, Severums can live for over 10 years. Maintaining a clean tank environment, providing a balanced diet, and minimizing stress are essential for their longevity and overall health.
