Species Overview

Róbalo blanco

The common snook is a prized inshore game fish found in tropical western Atlantic waters. It is highly sensitive to cold water and cannot survive temperatures below 12 degrees Celsius. Its lateral line is distinctive — a bold black stripe.

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.
