Description

The bigeye cichlid is a cichlid (Cichlidae) from northern South America. The species has a deep body with conspicuously large eyes and a highly protrusible mouth. It inhabits calm, often shady brooks and pools with amber-coloured water, slow current and a muddy bottom. As an ambush hunter it suddenly shoots its mouth forward to suck in small fishes and large invertebrates. As a cichlid it is a caring brood-tender. The species is harmless to humans.
