The Gold Severum, a variety of Heros efasciatus, is a captivating and popular cichlid species among aquarium enthusiasts, admired for its striking gold coloration and peaceful demeanor. Native to the Amazon Basin in South America, this variant has been selectively bred to enhance its vibrant gold hue, setting it apart from the wild-type Severums that exhibit green and brown color patterns. The Gold Severum is known for its disc-shaped body and gentle nature, making it a favored addition to large community aquariums with other similarly sized and temperamentally compatible fish.

Gold Severums are relatively large and require spacious aquariums to accommodate their size and ensure their well-being. They are social fish that appreciate the company of their own kind or other peaceful cichlids, though they can become territorial during breeding. An ideal aquarium setup for Gold Severums includes plenty of hiding spots created by rocks, driftwood, and robust, large-leafed plants. These features not only provide shelter and territories for the fish but also mimic the complexity of their natural habitat.

Maintaining optimal water quality is crucial for the health of Gold Severums, including stable water parameters and regular water changes to keep the environment clean and well-oxygenated. While adaptable to a range of conditions, they thrive in environments that closely resemble their native freshwater habitats in terms of temperature and pH balance.

The diet of the Gold Severum is omnivorous, with a natural inclination towards plant-based foods in the wild. In captivity, their dietary needs can be met with a variety of high-quality pellets, flakes, and live or frozen foods, such as bloodworms, brine shrimp, and daphnia. Incorporating vegetable matter, such as blanched spinach or zucchini, can also contribute to their nutritional well-being and vibrant coloration.

Breeding Gold Severums can be a rewarding experience for aquarists. They are substrate spawners, laying their eggs on flat surfaces such as rocks or driftwood. Both parents typically exhibit parental care, guarding the eggs and fry against potential threats. Providing a conducive breeding environment, with optimal water conditions and a nutritious diet, can encourage spawning behavior.

Caring for the Gold Severum requires attention to tank maintenance, including monitoring water quality and providing a balanced diet to ensure their health and longevity. Their peaceful nature makes them suitable for community tanks with other large, non-aggressive species, but aquarists should consider their potential size and dietary needs when selecting tank mates.

In summary, the Gold Severum, Heros efasciatus var., offers aquarists the opportunity to keep a visually striking and gentle species that adds beauty and a peaceful presence to the freshwater aquarium. While their care requires attention to dietary, environmental, and social needs, the rewards of keeping Gold Severums include the enjoyment of their stunning appearance and the enriching experience of observing their behaviors and interactions within the aquatic ecosystem.
