Red Spotted Severum Care Guide: Gentle Giant Cichlid
Among the South American cichlids kept in Singapore’s aquarium hobby, the red spotted severum occupies a unique position: large enough to be a true centrepiece fish, yet calm enough to coexist with species many cichlid keepers couldn’t dream of keeping together. Red spotted severum care rewards those who give it proper space and attention with a fish that recognises its keeper, begs at the front glass, and develops a personality that few purely decorative species can match. This guide from Gensou Aquascaping at 5 Everton Park, Singapore covers every practical aspect of keeping Heros efasciatus successfully in a Singapore home aquarium.
Appearance and the “Red Spotted” Distinction
The red spotted severum is a colour form rather than a separate species, distinguished by its warm golden-green body overlaid with vivid red-orange spots and tracery across the lower face and gill cover. Males develop the most intense spotting, particularly as they approach breeding condition; females are slightly less marked but still attractive fish. Adult size reaches 20–25 cm in well-maintained aquariums — considerably larger than most fishkeepers expect from a shop specimen at 5–7 cm. Buy with that adult size in mind, not the juvenile you see in the tank.
Tank Requirements
A minimum of 200 litres for a single adult, and 300 litres or more for a pair. This is not conservative advice — a red spotted severum in a tank under 150 litres will not reach its full size, will display chronic low-level stress, and typically develops digestive or immune issues within two to three years. For HDB flat residents in Singapore, a 200-litre tank already pushes floor load considerations; confirm your slab can handle the weight of a filled tank before purchasing.
Substrate should be sand or fine gravel — severum dig occasionally, and coarse substrate damages their mouths. Driftwood, large rounded stones, and robust plants like Echinodorus species complete a natural-looking setup. Java fern and anubias on wood survive the occasional plant rearranging these fish engage in.
Water Parameters
Target pH 6.0–7.5, temperature 26–30°C, and soft to moderately hard water (GH 4–12). Singapore’s soft tap water suits this species from the Amazon basin well. Temperature at the upper end of this range — 28–30°C — suits Singapore’s unheated or fan-cooled environments and accelerates growth and colour development. Maintain ammonia and nitrite at zero; nitrate below 30 ppm through regular water changes of 25–30% weekly.
Diet and Feeding
Severum are omnivores with a strong vegetable component to their natural diet. A staple of high-quality cichlid pellets — Hikari Cichlid Gold or similar — supplemented with blanched spinach, zucchini, peas, and occasional frozen foods works extremely well. Live or frozen bloodworms, brine shrimp, and krill can be offered weekly as protein supplements. Feed once or twice daily, only what the fish consumes in two to three minutes. Overfeeding is the single most common mistake with this species and leads to fatty liver disease in long-term captive fish.
Unlike many cichlids, red spotted severum enthusiastically eat plant matter and will graze aquarium plants. Factor this into your aquascape design.
Compatible Tank Mates
The severum’s relatively peaceful temperament for its size opens up compatibility options unusual in cichlid keeping. Large tetras — congo tetras, bleeding heart tetras — do well at the upper water column. Geophagus species make excellent bottom companions from the same South American region. Plecos, particularly bristlenose, survive well and help manage algae. Avoid small fish under 4 cm (at risk of being eaten), fin-nippers like tiger barbs, and aggressive cichlids that will overwhelm the generally passive severum. A matched severum pair forms a strong bond and will defend their territory during spawning.
Breeding
Sexing red spotted severum requires patience — reliable dimorphism only becomes apparent in adults. Males develop more intense red spotting on the face and longer dorsal and anal fin extensions. Conditioning a pair with heavy protein feeding at 28–30°C typically triggers spawning within weeks. The pair cleans a flat stone or the tank bottom and lays 200–500 eggs, which they guard with considerable dedication — rearranging the tank decor, darkening in colour, and challenging anything that approaches the spawn site. Both parents fan and guard the eggs through hatching; fry become free-swimming around five to six days post-hatch and accept baby brine shrimp immediately.
Long-Term Health Considerations
With proper care, red spotted severum live eight to ten years — a genuine long-term commitment. Hole-in-the-head disease (Hexamita-related pitting around the head and lateral line) is the most common chronic condition, almost always linked to nutritional deficiencies combined with nitrate accumulation. A varied diet and consistent water changes prevent it reliably. Regular observation matters; a fish that knows its keeper well will behave differently when unwell, and early detection of lethargy or off-feeding is the best disease management of all.
