Habitat
This species inhabits fast-flowing rivers and streams in the Amazon basin, preferring areas with submerged vegetation, rocks, and woody debris for cover. It is commonly found in warm, freshwater environments of South America, including the Negro, Orinoco, and surrounding river systems. Geographic preferences include tropical regions with acidic, soft water.
Diet
The Pinktail Chalceus primarily feeds on insects, small fish, and crustaceans, often capturing prey near the water's surface. It exhibits opportunistic feeding behavior, hunting in schools during the day to ambush smaller organisms. Feeding activity peaks in the early morning and late afternoon when prey is most abundant.
Behavior
Pinktail Chalceus are schooling fish that form groups for protection and foraging, making them highly social in their aquatic environments. They are diurnal, active during daylight hours for feeding and exploring, while resting in sheltered areas at night. This species can display territorial behavior around prime feeding spots, especially during breeding periods.
