The Red Severum, also known as the Red Shoulder Severum or Heros efasciatus, is a vibrant and beautiful cichlid species that adds a splash of color to any aquarium. Here's some information about the Red Severum:

• Appearance: The Red Severum displays a stunning coloration with a reddish-orange body and distinctively pronounced red or orange markings on its shoulders. As they mature, the colors become more vibrant and pronounced. They have a laterally compressed body with a slightly elongated shape and a pointed dorsal fin. The Red Severum is a visually striking fish that can become the focal point of your aquarium.

• Size: The Red Severum typically reaches a size of about 7-8 cm (2.8-3.1 inches) in length when fully grown. However, it's important to note that they can grow larger with proper care and a suitable environment. Providing ample space in the aquarium is essential to accommodate their growth.

• Habitat and Tank Requirements: Red Severums are native to the Amazon Basin in South America, where they inhabit slow-moving rivers and tributaries. In captivity, they require a spacious aquarium with plenty of swimming space and hiding spots such as caves, rocks, and driftwood. A minimum tank size of 75 gallons is recommended to provide them with adequate space. The water temperature should be kept between 24°C and 28°C (75°F to 82°F), and the pH level should be around neutral to slightly acidic.

• Behavior and Compatibility: Red Severums are generally peaceful and can be kept in a community aquarium with other non-aggressive fish species of similar size. However, it's important to note that as they grow, they may become territorial and display aggression towards other fish. It's best to provide them with plenty of hiding spots and enough space to establish their own territories. Avoid keeping them with small, delicate fish that may become targets for aggression.

• Diet: Red Severums are omnivorous and will readily accept a variety of foods. Offer them a balanced diet that includes high-quality pellets or flakes, supplemented with live or frozen foods such as bloodworms, brine shrimp, and small insects. Additionally, incorporating some vegetable matter into their diet, such as blanched spinach or spirulina-based foods, is beneficial for their overall health.

• Care and Maintenance: Maintaining good water quality is essential for the health of Red Severums. Regular water changes, filtration, and monitoring of water parameters (ammonia, nitrite, nitrate, and pH) are important to keep the environment clean and stable. Providing a well-balanced diet, suitable hiding spots, and regular observation will contribute to their overall well-being.

• Breeding: Red Severums are known to exhibit parental care and can be bred in captivity. A separate breeding tank with appropriate hiding spots, flat rocks, or slate should be set up for breeding purposes. The water temperature can be slightly increased, and frequent water changes can help simulate the rainy season and encourage breeding behavior. The parents will guard and care for their eggs and fry.

The Red Severum is a stunning and charismatic fish that brings both beauty and personality to an aquarium. With their vibrant colors and engaging behavior, they are sure to captivate any observer. Remember to provide them with suitable tank mates, a well-balanced diet, and a well-maintained environment to ensure their optimal health and happiness.
