Species Overview
Common Goldfish
The goldfish was one of the first fish to be domesticated, with selective breeding in China dating back over 1,000 years. Despite common misconceptions, goldfish can live 10-15 years with proper care and require far more space than a small bowl.
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.
