Severum (Heros severus)

Severum Tropical Fish Learn all about the Severum's feeding habits and food types, its behaviour, its origins, its natural habitats, is it male or female, breeding advice and information, suitable tank mates, its sizing and growth range, minimum tank size, water PH and more. Use our fish community creator tool to plan your tank set up and ensure that the Severum is the right fish for your aquarium.

The Severum is one of the more peaceful larger cichlids and can be kept with most other peaceful, moderately sized fish. When young and first introduced to the aquarium the Severum can seem a little timid and nervous but given time its confidence will grow and they will learn to 'know' their owners. The Severum is occasionally territorial but only aggressive when defending a breeding site or young fry. Although the Severum will adapt well to hard water, over a longer period it will do much better in soft-medium water. Provide hiding spots amongst rocks, wood, and hardy plants. A gold variety is also available.

The ‘common’ severum is not H. severus. The commonly kept ‘wild’ severum is H. liberifer, while the various man-made varieties come mainly from H. efasciatus/appendiculatus.
