Species Overview
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.
Wels Catfish
The wels catfish is the largest freshwater fish in Europe, capable of exceeding 5 meters. Found in large rivers and lakes across the continent, it has been documented beaching itself to catch pigeons. It can live over 80 years.
