Severum Tank Setup and Care

Severums are suitable for large community cichlid tanks. They require stable, warm water. Adequate swimming space is important. Moderate filtration is sufficient.

Use sand or smooth gravel substrate. Decorate with driftwood and rocks. Plants may be eaten over time. Provide open areas.

Maintain regular water changes. Avoid sudden parameter shifts. Stable conditions reduce stress. They adapt well to captivity.

Severums are interactive and visible. They benefit from consistent care. Peaceful setups enhance behavior. Good husbandry ensures longevity.

Severum Diet and Feeding

Severums are omnivorous with herbivorous leanings. They accept pellets and flakes. Vegetable matter is important. Use high-quality cichlid foods.

Supplement with spinach and peas. Offer frozen foods occasionally. Avoid excessive protein. Feed once or twice daily.

Balanced diet supports digestion. Overfeeding causes health issues. Juveniles need more frequent meals. Adults prefer routine.

Observe feeding habits. Adjust portions as needed. Remove uneaten food. Diet variety improves vitality.

Severum Breeding and Reproduction

Severums form monogamous pairs. They choose flat surfaces to spawn. Both parents guard eggs. Spawning follows water changes.

Eggs hatch in a few days. Parents protect wrigglers. Fry become free-swimming soon. Provide suitable fry food.

Aggression increases during breeding. Remove other fish if needed. Maintain excellent water quality. Parental care is reliable.

Breeding is achievable for hobbyists. Stable conditions are key. Stress may cause egg loss. Success depends on pair bonding.
