The Aimara jeju (Hoplerythrinus unitaeniatus) is a freshwater fish of the family Erythrinidae that grows up to 29 cm.
Description
The aimara jeju is a cylindrical predator of the family Erythrinidae reaching about 29 cm. The elongate, brownish body bears a dark lengthwise stripe and a conspicuous eyespot on the gill cover. Like relatives it can gulp air with its muscular swim bladder and so survive in warm, oxygen-poor swamp water, and wait out short droughts. The species comes from Central and South America and lives in slow, densely vegetated water of swamps, pools and rivers. As an ambush predator it lies still among plants and hunts fish, insects and crustaceans. The male guards a nest pit with eggs and young. It is a locally valued food fish and occasionally appears in the aquarium.
