Species Overview

Perca-gigante

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.

Discus

The discus is often called the 'King of the Aquarium' for its disc-shaped body and stunning color patterns. Native to the Amazon floodplains, it requires warm, soft, acidic water and feeds its fry with a mucus secretion from its skin.
