Fischprofil
- Temperament
- Semi-aggressive
- They are renowned for their peaceful, almost dog-like temperament and intelligence. Severums quickly learn to recognize their owners and will often beg for food at the front of the glass. While peaceful, they have a robust build and will firmly defend themselves if bothered by aggressive fish. Their calm demeanor makes them a favorite among South American cichlid enthusiasts.
- Diät
- Omnivore
- Severums are omnivorous with a strong preference for plant matter in their daily diet. They will readily consume high-quality cichlid pellets, spirulina flakes, and fresh blanched vegetables like zucchini or peas. Meaty foods such as bloodworms and brine shrimp should be offered sparingly as treats. Live aquarium plants are often viewed as a food source and may be eagerly consumed.
- Lebenserwartung
- 10-12 years
- Erwachsenengröße
- 25 cm
- Geschlechterverhältnis
- Pair
- Sexing severums can be challenging, but mature males often develop distinct facial markings and extended fin trailers. Females are generally slightly smaller and have a plainer facial pattern without the intense worm-like markings. They are best kept in pairs or as a single focal point fish in a community setting. Keeping multiple males may lead to mild territorial posturing in smaller tanks.
- Fütterungsfrequenz
- Twice daily
- These cichlids thrive when fed one to two times a day with a carefully balanced diet. Offer only what they can consume within a few minutes to prevent food decay and water fouling. Growing juveniles can be fed slightly more often to support healthy development. Providing a scheduled fasting day once a week can help prevent digestive issues.
- Bioload
- Medium to High
- Severums are substantial fish that produce a considerable amount of waste as they grow. Adequate filtration, such as a large canister filter, is necessary to maintain excellent water quality. Weekly water changes of at least thirty percent are recommended to keep nitrates low. Proper tank maintenance ensures these cichlids do not suffer from stress-related illnesses.
- Fluss
- Stagnant
- They prefer gentle to moderate water flow, mimicking the sluggish rivers and calm lakes of their native South America. Overly turbulent water can cause them stress and make it difficult for them to swim naturally. Standard filtration flow is usually adequate without the need for additional powerheads. Ensure there are calm areas decorated with driftwood for them to rest.
- Sprungrisiko
- No
- Reproduktion
- Oviparous
- Depending on the exact species, severums are either substrate spawners or specialized mouthbrooders. They form strong monogamous pairs and display intense parental care during the breeding process. Substrate spawners will clean a flat rock to lay eggs, while mouthbrooders will protect the fry inside their mouths. Breeding pairs can become territorial, so a separate breeding tank is often recommended.
- Kompatibilität & Tankkameraden
- Semi-aggressive
- Unlike many large cichlids, severums are remarkably peaceful and make great additions to large community tanks. They can be safely housed with other peaceful to semi-aggressive fish of similar size. They generally ignore smaller fish, though extremely tiny species might occasionally be eaten by large adults. They pair well with peaceful catfish, large tetras, and other mild-mannered cichlids.
- Tankfüllstand
- Middle/Bottom
- Severums are versatile swimmers that utilize the middle and lower levels of the water column. They enjoy navigating through complex environments made of submerged branches, roots, and smooth rocks. They will occasionally venture to the surface during feeding time. Providing vertical structures gives them a sense of security and encourages natural behavior.
