Species Overview

Betta

The Siamese fighting fish is famous for its vibrant colors and flowing fins, developed through centuries of selective breeding. Males are highly territorial and will flare their gill covers at rivals. They possess a labyrinth organ for breathing atmospheric air.

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.
