The Red Spotted Heros Severum is renowned for its peaceful and mild-mannered behavior, making it a suitable addition to community aquariums. While they may display some territorial tendencies during breeding, these fish generally coexist harmoniously with other non-aggressive species. They are also known for their curiosity and interactive nature, often exploring their surroundings and interacting with tank decorations.


In their natural habitat, Red Spotted Heros Severum are omnivores, feeding on a varied diet of insects, small crustaceans, and plant matter. In a home aquarium, they can be offered high-quality pellets, flakes, and live or frozen foods such as brine shrimp, bloodworms, and daphnia. Incorporating plant matter into their diet through blanched vegetables like spinach and zucchini ensures a well-balanced nutritional intake.

Keeping the Red Spotted Heros Severum at home

Creating an optimal environment for Red Spotted Heros Severum requires careful consideration of tank setup, water parameters, and tank mates. Here are some essential guidelines to ensure their well-being:

Tank mates: Red Spotted Heros Severum are generally compatible with other peaceful cichlid species, tetras, catfish, and similarly sized non-aggressive fish.
Breeding: To encourage breeding behavior, provide flat rocks or spawning sites. Be prepared to separate breeding pairs to avoid potential aggression.
