Species Overview
Corydoras
The peppered corydoras is a peaceful bottom-dwelling catfish native to South American rivers. It uses its barbels to sift through substrate for food and should be kept in groups of six or more. It can gulp atmospheric air in low-oxygen conditions.
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.
