Species Overview
Cherry Barb
The cherry barb is a small, colorful fish native to Sri Lanka's shaded forest streams. Males develop an intense cherry-red coloration during breeding. Listed as Vulnerable due to habitat loss and over-collection for the aquarium trade.
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.
