Habitat
The marbled jacunda inhabits freshwater rivers, streams, and flooded forests in the Amazon basin, particularly in Brazil's Sucunduri, Amazon, Madeira, and Tocantins rivers. It prefers slow-moving waters with abundant vegetation and submerged structures for cover. These areas provide both hunting grounds and protection from predators.
Diet
The marbled jacunda primarily feeds on small fish, insects, and crustaceans, using its ambush tactics to capture prey. It is an opportunistic carnivore, often hunting during the day in shallow waters. Feeding behavior includes lying in wait among vegetation before striking quickly.
Behavior
Marbled jacundas are solitary and territorial fish, defending their home ranges aggressively against intruders. They are diurnal, spending much of their time hiding in vegetation and ambushing prey. This species exhibits parental care, with males guarding eggs and fry after spawning. They are known for their quick, darting movements when threatened.
