Species Overview
Barramundi
The barramundi is a large, catadromous predator native to the Indo-West Pacific. It is a protandrous hermaphrodite, beginning life as male and transitioning to female after several years. Highly prized in both sport fishing and aquaculture.
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.
