What Green Severum look like

The Green Severum (Heros severus) exhibits a laterally compressed, oval body shape that can reach a maximum adult size of approximately 10 inches (25 cm). This species displays sexual dimorphism, with males typically being larger and more vibrantly colored, particularly during breeding seasons, while females tend to be slightly smaller and less colorful. The coloration is predominantly olive green, adorned with distinct red spots on the cheeks and throughout the body, providing a striking contrast. Notable morphological features include a rounded dorsal fin that extends from the nape to the caudal fin, and a well-developed adipose fin. The lateral line is prominent, facilitating the detection of vibrations in the water, while the dentition is characterized by pharyngeal teeth adapted for crushing food. Defensive adaptations include a robust body and the ability to display aggressive postures when threatened, particularly during breeding periods.

Behavior & temperament

The Green Severum is generally a peaceful species, often found in small groups or pairs, though it can exhibit territorial behavior, particularly males during breeding. This fish primarily occupies the mid to lower levels of the water column, exhibiting a semi-benthic lifestyle. Breeding behavior is characterized by substrate spawning, where the female scatters eggs on flat surfaces, and both parents exhibit protective behaviors towards the fry. The Green Severum is known for its relatively calm temperament, although it can become aggressive if provoked or during the breeding season, necessitating careful tankmate selection to avoid stress.

Diet & feeding

In the wild, the Green Severum is an omnivore, feeding on a varied diet that includes plant matter, small invertebrates, and detritus. In captivity, it requires a balanced diet consisting of high-quality pellets, frozen or live foods, and vegetable matter to meet its nutritional needs.
