Cuisine & Edibility

Angelfish

Not consumed — a graceful ornamental cichlid valued for its triangular body shape and striking vertical banding; widely kept in freshwater community tanks.

Critically Endangered — consumption is illegal throughout its range. Historically prized for its delicate flesh and black caviar; now one of the world's most threatened fish species.

Species Overview

Angelfish

The freshwater angelfish is a majestic cichlid with a laterally compressed body and long, flowing dorsal and anal fins. Native to the Amazon basin, it has been selectively bred into numerous color varieties including marble, koi, and platinum.

European Sturgeon

The European sturgeon is a critically endangered anadromous fish that can live over 100 years. Once abundant in European rivers, it is now restricted to a small population in the Gironde estuary. Its eggs are harvested as beluga-grade caviar.
