Species Overview
Peacock Bass
The peacock bass is the crown jewel of Amazon basin sport fishing. Despite its name, it is actually a large cichlid. Known for explosive topwater strikes and powerful, drag-screaming runs in tropical rivers and lagoons.
Plecostomus
The common pleco is a large armored catfish native to South America. Often purchased as an algae eater, it can outgrow most home aquariums. Its sucker-like mouth allows it to rasp algae from surfaces and anchor itself in fast-flowing currents.
