Cuisine & Edibility

Discus

Species Overview

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.

Electric Eel

Despite its name, the electric eel is not a true eel but a knifefish. It can generate electrical discharges of up to 860 volts to stun prey and defend itself. About 80% of its body is dedicated to three electric organs.
