Goldfish

The goldfish (Carassius auratus) is an ornamental fish in the Cyprinidae family, known for its attractive appearance and ease of care. Originally native to east Asia, where it was first domesticated, goldfish have been popular pets for centuries due to their hardiness and longevity. In addition to their bright colors and graceful swimming patterns, goldfish also display an often playful and social behavior, frequently thriving in groups with other goldfish or peaceful aquatic species.

The caption reads in the original French: Dorade (Cyprinus auratus).
NB: Although the word dorade in French currently translates to sea bream, it should be understood here as the short form of dorade de Chine, an antiquated name for goldfish.
