Severums are native to the Amazon and Orinoco river systems, where they inhabit slow-moving waters associated with submerged vegetation, roots, driftwood, and soft substrates.\u003c\/p\u003e\n\u003cp\u003eThe body typically develops a rich yellow to golden coloration, sometimes accompanied by subtle orange or olive shading. Fine iridescent markings may appear across the face and flanks, while the fins can develop contrasting yellow, orange, or reddish highlights. Colour intensity generally increases with maturity, conditioning, social status, and stable environmental conditions.\u003c\/p\u003e\n\u003cp\u003eBehaviour is intelligent, deliberate, and generally peaceful for a medium-to-large cichlid. Individuals are naturally inquisitive and frequently explore their surroundings, particularly around driftwood, plants, and other structures. Mature specimens may establish territories and can become more assertive during breeding, while bonded pairs may demonstrate strong parental care.\u003c\/p\u003e\n\u003cp\u003eSpecimens supplied are lab-reared and system-acclimated within controlled, closed-system environments, minimizing early-life stress and supporting reliable long-term adaptation to aquarium conditions.
