Species Overview

Crapet arlequin

The bluegill is the most common sunfish in North America and often the first fish a young angler catches. Its deep body, dark ear flap, and iridescent blue-green colors make it easy to identify. A fierce predator of insects despite its small size.

Poisson rouge(=Cyprin doré)

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.
