Angler's Summary
Known Range Behavior Notes Habitat Common Names IGFA records
Countries: Peru, Ecuador, Columbia, Brazil

River Basins: Rio Solimoes - Amazonas basin to Marajo Island (near mouth of Amazon). Widespread throughout Amazon basin.
Where found with congeners (other species of peacock bass), such as C. temensis, C. monoculus tends to occupy the shallower or more structure dense areas of the fishery, especially related to dense tangles of wood. Primarily occupies lentic (slow or still water) environments in floodplain lakes and backwater river lagoons, both blackwater and whitewater. popoca

Fishing Tactics

In waters where C. temensis is present, C. monoculus tends to occupy lentic (slow) waters with the most dense structure. It readily strikes subsurface lures, including jigs and flies and will sometimes take Zara Spooks and small woodchoppers on the surface. In Rio Solimoes waters where C. temensis is not present, it can be found guarding fry and will readily attack large surface plugs. Angling characteristics in other regions are not known to us.
