Artbeschreibung
Geographical Origin and Habitat: A freshwater species; the enclosure should provide stability, oxygenation, space and shelter consistent with its behaviour without turning one habitat description into a mandatory recipe.
Taxonomy and Morphology: The accepted scientific name is Heros severus; the verified classification records genus Heros, family Cichlidae, subfamily Cichlinae, order Cichliformes. Historical names remain searchable as synonyms rather than separate species.
Social Behavior: Severum (Banded Cichlid) can be kept alone or in a compatible pair or group. The minimum reference is one individual; sex, maturity and available space can require a more conservative composition. Observe access to food, resting behaviour, chasing and use of shelter. Isolation, persistent competition or aggression means the number, composition or environment needs to be corrected.
Coloration and Sexual Dimorphism: Colour and shape can vary with age, sex, physiological state and environmental conditions. Identification and sexing require recognized species-level characters; one appearance or photograph is not enough.
Pflege, Zucht und Mitbewohner
Aquarium Setup: Severum (Banded Cichlid) needs an aquarium of at least 300 litres, sized for adult body size and a minimum group of one individual. Filtration, shelter and swimming room must match the species and the actual number kept. Volume alone does not make an enclosure suitable: tank shape and length, usable area, oxygenation and the ability to separate territories must reflect adult behaviour.
Diet and Feeding: The recorded diet is omnivorous. Offer appropriately sized foods varied within that category, and adjust quantity and frequency from actual intake, body condition and leftovers. One food or a fixed schedule is not suitable for every age and situation.
Water Quality: Maintain stable, well-oxygenated water appropriate to a freshwater species; the card's reference values are 25–30 °C, pH 5–7. Verify conditions with reliable tests and size maintenance and filtration to the actual load. Ranges are not automatic thresholds for treatment or rapid chemical correction.
Compatibility and Cohabitation: The cohabitation profile is a species to combine with caution, with a generally semi-aggressive temperament. Keep at least one individual; tankmates, stocking density and decor must allow escape, rest and feeding without excessive competition. Watch interactions especially during feeding, maturity and breeding. Persistent chasing, injury or exclusion from food requires a change in stocking or layout, or separation of the animals.
Aquarium Breeding: The recorded reproductive profile is “oviparity”. Breeding should be attempted only with healthy adults, separation capacity and a plan for eggs or young. Do not treat unverified triggers, sex ratios or hatch times as universal for this species.
Risks and Diseases: Prevent problems through quarantine of new arrivals, stable water, appropriate feeding and daily observation. Similar signs can have different causes, so check parameters, history and diagnosis before medication. Follow the product label and qualified aquatic-veterinary advice; there is no universal reduced dose for a species or family.

Fischprofil
- Temperament
- Semi-aggressive
- Severum (Banded Cichlid) has a generally semi-aggressive temperament. Insufficient space, an unsuitable social ratio or incompatible tankmates can substantially change observed behaviour.
- 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
- 8-10 years
- Erwachsenengröße
- 25 cm
- Geschlechterverhältnis
- Flexible
- Severum (Banded Cichlid) can be kept alone or in a compatible pair or group. The reference minimum is one individual and must not be read as permission to overcrowd the aquarium.
- 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
- 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
- With caution
- The cohabitation profile is a species to combine with caution, with a generally semi-aggressive temperament. Keep at least one individual; tankmates, stocking density and decor must allow escape, rest and feeding without excessive competition. Watch interactions especially during feeding, maturity and breeding. Persistent chasing, injury or exclusion from food requires a change in stocking or layout, or separation of the animals.
- 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.
