The fish, up close
The Green Severum, scientifically known as Heros severus, is a stunning and peaceful cichlid species native to the slow-moving waters of the Amazon basin in South America. Known for their vibrant green and gold colouration, Green Severums have a distinctive oval-shaped body with extended fins. Juveniles often exhibit a dark vertical banding pattern that fades as they mature. These fish are popular among aquarists for their beauty and relatively calm demeanor, making them an excellent addition to community tanks with other non-aggressive species.
Care guide
Use these notes to shape a setup around the fish, then speak with our team about the tank you have in mind.
Plan your setupBehaviour
Green Severums are generally peaceful and can be kept with other non-aggressive fish species. However, they can become territorial, especially during breeding. It's recommended to provide ample hiding spots and territories within the aquarium to reduce aggression. They may also dig in the substrate, so plants and decorations should be securely anchored.
Tank planning
Maintaining stable water parameters is crucial for the health of Green Severums. They prefer slightly acidic to neutral water with temperatures between 24-28°C. Regular water changes and a well-filtered tank are essential. Tank lighting should be moderate, and the aquarium should have plenty of plants and driftwood to mimic their natural habitat.
