Habitat
Yellowfin river pellona primarily inhabits freshwater rivers and streams in tropical South America, including the Amazon basin and Orinoco River. They prefer areas with moderate current and abundant vegetation, such as flooded forests and river margins. These environments provide cover and food sources in warm, murky waters.
Diet
This species feeds mainly on small fish, insects, and zooplankton, often capturing prey in schools. They exhibit opportunistic feeding behavior, primarily during dawn and dusk in river currents. Feeding involves rapid pursuits and filter-feeding on plankton.
Behavior
Yellowfin river pellona are schooling fish that form groups for protection and feeding, often swimming in mid-water columns. They are active during the day, showing territorial behavior around feeding areas, and migrate upstream during the rainy season. This species is generally wary of threats, quickly dispersing when predators are near.
Conservation Status
Listed as Not Evaluated by IUCN.
