Taxonomy

• Kingdom: Animalia
• Phylum: Chordata
• Class: Actinopterygii
• Order: Perciformes
• Family: Cichlidae
• Genus: Heros
• Species: H. severus

Physical Characteristics

The Severum is a large and robust cichlid, with adult specimens reaching an average length of 12-15 inches (30-38 cm). Its body is elongated and laterally compressed, with a distinctive hump on the head. The fins are large and flowing, contributing to the fish's overall grandeur.

The most striking feature of the Severum is its coloration. The base color can vary from yellowish-orange to reddish-brown, while the body is adorned with iridescent blue-green scales that shimmer under light. A dark stripe runs horizontally through the eye, extending to the base of the tail fin.

Behavior

The Severum is a semi-aggressive cichlid, meaning it can be territorial and aggressive towards other fish of its own species and similar size. However, it is generally peaceful towards other fish that are smaller or belong to different species.

Severums are intelligent and inquisitive fish that enjoy exploring their surroundings. They are known to be opportunistic feeders, readily accepting a wide variety of live, frozen, and flake foods.

Sexual Dimorphism

Male and female Severums exhibit subtle sexual dimorphism. Males tend to be larger than females, with more intense coloration and a more pronounced hump on their heads. Additionally, the anal fin of males is longer and more pointed than that of females.

Habitat and Distribution

The Severum is native to the Orinoco and Amazon River basins of South America. It inhabits a variety of habitats, including flooded forests, slow-moving rivers, and oxbow lakes. The Severum prefers areas with abundant vegetation and submerged logs for shelter.

Diet

Severums are omnivorous, meaning they feed on both plant and animal matter. In the wild, their diet consists of insects, worms, small fish, and fruits. In captivity, they can be fed a variety of foods, including pellets, flake food, frozen bloodworms, and live brine shrimp.

Water Quality Parameters

Providing the correct water quality is crucial for the health and well-being of Severums. The ideal parameters are as follows:

Tank Requirements

Severums require a spacious tank with plenty of room to swim and establish territories. A minimum tank size of 55 gallons (208 liters) is recommended for a single Severum, while a larger tank is required for multiple individuals.

The tank should be heavily planted with live or artificial plants to provide hiding places and create a natural environment. Submerged logs and rocks can also be added to the tank for additional shelter and decoration.

Tank Mates

Choosing suitable tank mates for Severums is important to ensure a harmonious and healthy environment. Good tank mates include:

• Tetras
• Barbs
• Corydoras catfish
• Plecos

Avoid keeping Severums with aggressive cichlid species or fish that are much smaller in size.

Filtration and Lighting

Severums are sensitive to poor water quality, so efficient filtration is essential. A canister filter or hang-on-back filter with a biological media is recommended.

Lighting is also important for the well-being of Severums. They prefer moderate lighting, so avoid using high-intensity lights. Natural sunlight can also be beneficial, but ensure that the tank is not exposed to direct sunlight for extended periods.

Common Diseases

Severums are generally hardy fish, but they are susceptible to certain diseases, including:

• Ich (White Spot Disease)
• Fin Rot
• Dropsy
• Bacterial Infections

Proper water quality, stress reduction, and a healthy diet are the best ways to prevent diseases in Severums. If you suspect your Severum is sick, consult with a veterinarian or experienced aquarist for appropriate treatment options.

Breeding

Severums are relatively easy to breed in captivity. Breeding pairs can be established by introducing several young Severums into a breeding tank and allowing them to form their own pairs.

The breeding process usually starts with the male courting the female. He will display bright colors and perform a dance in front of her. If she is receptive, she will respond by laying eggs on a flat surface. The male will then fertilize the eggs.

Severums are excellent parents and will guard the eggs and fry (baby fish) until they are free-swimming. The fry can be fed brine shrimp or infusoria until they are large enough to accept flake food.

Tips and Tricks

• Provide plenty of hiding places for your Severums to reduce stress and aggression.
• Keep the water quality pristine by performing regular water changes and cleaning the filter regularly.
• Feed your Severums a varied diet to ensure they are getting the nutrients they need.
• Monitor your Severums closely for any signs of disease and seek treatment promptly if necessary.
• Be patient when breeding Severums. It may take several attempts before you are successful.

Common Mistakes to Avoid

• Overcrowding the tank with too many Severums or other fish.
• Using inappropriate tank mates that can harm Severums.
• Neglecting water quality by failing to perform regular water changes and cleaning.
• Overfeeding your Severums which can lead to obesity and health problems.
• Not quarantining new fish before adding them to the tank to prevent the introduction of diseases.
